Hey there Lukie,
Your calculations are fine however near the end the equation x = pi2/16 makes invalid, unproven assumptions. The correct equation for x = (1 - Pi2/16)^.5.
So another Pi = 3.1446 nitwit has crawled out of the dark shadows debunking traditional Pi = 3.14159 however none of you bozo's have ever proven traditional Pi = 3.14159 is invalid! That's because traditional Pi = 3.14159 is the best estimate of true Pi; common knowledge among every scientist, engineer, mathematician, and likely every school teacher, in the entire world.
All you Pi = 3.1446 bozo's do is play with your Kepler triangles and golden ratios like a child with toy blocks never accomplishing anything constructive. If you had any intelligence you'd know Pi = 3.1446 is fake; its impossibly large. So you've already proven you're another idiot within the FIGU Community; adding to the growing list of morons.
The Right Angle Altitude Theorem which you claim is the root to faking Pi = 3.1446, is a straight-line concept and offers no insight into the true and actual length of a curved line. Again, as always, you bozo's try to sneak your way into solving for Pi without resolving the actual distance of a curved line. If finding Pi by circumferential distance is the objective, then the first step is to estimate the circle circumference "C" without using Pi - because Pi is unknown. Both C and Pi are unknown, so first estimate C, and use the estimated C to estimate Pi. You can't 'cheat' around this - bozo.
Welcome, to the exclusive FIGU Radicals club - you'll fit right in! Membership is primarily open to anyone who proposes the true and correct Pi = 3.1446, contrary to statements made by Ptaah and Billy Meier as well as the fact that every scientist, mathematician and engineer in the entire world knows Pi = 3.1446 is a hoax. So you qualify with your Pi, 4/sqrt(phi), 3.1446 based on circumference. nonsense!
Its important to do your share as a FIGU Radical in order maintain the mindless babble and growing archive, the true and correct Pi = 3.1446. A little disappointed that your very first post had no pretty drawings showing a fake Pi = 3.1446 proof? With a little practice you will master the FIGU Radical fake Pi = 3.1446 protocol. Arthur likes copying other peoples faked proofs, Jude like posting several feet of calculator images with no explanations, and Liddz prefers to copy/paste from an extensive inventory of fake Pi = 3.1446 nonsense equations and calculations, and in time you will discover your own unique style to fake the Pi = 3.1446 proof. A little advice you will find its easier to fake your proofs using the coloring techniques mastered by the fraud artist Harry Lear.
My understanding is that in order to maintain your good standings within the FIGU Radical club, its preferred not to have a university education in mathematics (probably why I'm not welcome), however being a know-it-all on the subject is mandatory and also, the FIGU Radicals consider it sacrilege to learn and understand how traditional Pi = 3.14159 is calculated; you could be summarily disbarred if they ever found out you tried to understand the truth. The whole point of being a FIGU Radical is to maintain the Pi = 3.1446 hoax proposed by the master scam artist Harry Lear.
Just throwing it out there, but optionally consider going to back to school, learn basic mathematics, and finally understand why Pi = 3.14159 is the best estimate of true Pi, and then contribute back to society instead of negatively promoting the Pi = 3.1446 lie. In fact once you attend school, and learn Pi = 3.14159, you could potentially get a job with NASA - imagine that, but as a FIGU Radical promoting Pi = 3.1446; guarantee you'll never get a job in a scientific field (lol).
The FIGU Community seems to attract a disproportionate number of idiots pushing the Pi = 3.1446 LIE for some reason, like months to flame. And their persistence in propagating the Pi = 3.1446 LIE feels deliberately coordinated with over 200 - posts on this Pi topic already.
As a math professional, feel obligated to stand-up for Billy Meier's correct and accurate statements the true and correct Pi is UNKNOWN in view of the true and correct Pi = 3.1446 LIES perpetrated against Billy by the FIGU Radicals, Michael Horn and Christian Frehner who DO NOT accept the truth about Pi according to Billy Meier.
Billy has never been wrong, yet there seems to be overwhelming forces at work who will stop at nothing to discredit Billy Meier statements Pi is UNKNOWN by a group of foolish FIGU Radical folks within the FIGU Community who refuse to accept Billy's knowledge and wisdom on the subject of Pi and lack the intelligence to know any better.
There is something really fishy and corrupt going on here to discredit Billy Meier's truthful and accurate statements true Pi is UNKNOWN with this ridiculous true and correct Pi = 3.1446 hoax. The FIGU Radicals, promoting Pi = 3.1446 are in fact deceivers, and ABSOLUTE LIARS contradicting Billy Meier's statement the true and correct Pi is unknown. Reading CR 712 with a little intelligence, Ptaah makes it clear traditional Pi = 3.14159 is the most accurate estimate of true Pi. You Fraudsters are a determined bunch that's for sure however the truth will prevail - as always.
Harry Lear is not only a FRAUD but a LIAR and is easily proven
In January 2018 Harry sent a letter to then president Donald Trump with numerous false claims he not only solved the true and correct Pi = 3.1446, and that the Plejaren were astounded by his brilliance, but what really sticks out, is Harry also claimed the Plejaren were using his true and correct Pi = 3.144605511.
Excerpt from Harry's Letter to President Trump claiming the Plejaren were using his true and correct Pi = 3.1446


Ten months after Harry sent his letter to President Trump, in November 2018, Billy Meier publishes Contact Report 712 where Ptaah states the true and correct Pi has not yet been calculated correctly and exactly on Earth.
Excerpt from CR 712 Ptaah States True and Correct Pi NOT Yet Known on Earth


Then a few months later in August 2019, in Contact Report 722, Billy echos Ptaah's statements in CR 712, that the true and correct Pi is still unknown to Earth humans.
Excerpt from CR 722 Billy States True and Correct Pi NOT Yet Known on Earth


This clearly exposes Harry's bold-faced lies not only did he falsely claim he solved the true and correct Pi = 3.1446 but he also lied about the Plejaren were using his true and correct Pi = 3.1446 because 10-months after Harry's letter to Trump, Ptaah states in CR 712, Earth humans haven't calculated the true and correct Pi, and Billy repeats Ptaah's message 9-months later in CR 722 on August 8, 2019, (as if to drive the point home), that the true and correct Pi is UNKNOWN.
Since both Ptaah and Billy confirm Earth humans have not yet found the true and correct Pi it proves Harry Lear lied when he had earlier claimed to have solved the true and correct Pi = 3.1446 and the Plejaren were using his true and correct Pi = 3.1446. This demonstrates Harry Lear's deceptive, dishonest behavior as a unscrupulous LIAR.
There are other obvious LIES in Harry's letter to President Trump, that contradict the Contact Reports statements by Billy, the Plejaren or just simply fabricated in order to sway anyone into believe his nonsense true and correct Pi = 3.1446 which both Ptaah and Billy says Earthly humans have not solved at this time, however it only takes a little investigation to expose the fraud and reveal Harry's dishonest nature. If Harry was truly honest this lie simply would not exist yet here it is so blatantly obvious for anyone to see.
How Harry's fraud and lies have been suppressed, his false credibility allowed to propagate, and fester, within the FIGU Community with absolutely no regard for the truth or accountability, is a truly remarkable scam to have pulled off. Harry truly is the modern day Pied Piper. Well done Harry - You're a true scam artist!

We can thank both Michael Horn and Christian Frehner for their monumental stupidity helping to promote the true and correct Pi = 3.1446 nonsense within the FIGU Community. Neither Christian nor Micheal are knowledgeable in mathematics and both completely unqualified to make any statements about the accuracy of the Pi number other than what has been shared by Billy Meier in the Contact Reports specifically CR 712 and 722 which state the true and correct Pi is unknown.
Instead of reading and understanding Billy Meier's information about Pi in the Contact Reports 712 & 722, Michael and Christian choose to foolishly promote Harry-the-bozo-Lear's true and correct Pi = 3.1446 nonsense, as recently as June 2024.


Christian Frehner, a FIGU Core member, who thinks he's smarter and wiser then Billy Meier, foolishly published Bulletin #77 supporting Harry Lear's true and correct Pi = 3.1446 nonsense instead of referencing Billy Meier's information about Pi where Billy makes it perfectly clear the true and correct Pi is unknown. As a FIGU Core member, Christian, should be supporting Billy Meier rather than contradicting Billy Meier.
Here is an example of a FIGU Core member who doesn't understand perhaps he should be supporting and sharing Billy Meier's truthful knowledge including Billy's information the true value of Pi is unknown, but rather decides instead to promote the Pi = 3.1446 lie fabricated by a dimwitted human being of Earth. Honestly if you're a FIGU Core member you should really only trust the information shared by Billy Meier and NO ONE ELSE!
Both Michael Horn and Christian Frehner, have fallen victim to the Pi = 3.1446 lies spread by a human being of Earth, rather than listening to and trusting what Billy Meier and Ptaah state about Pi. The person they foolishly trusted which such a ridiculous claim the true and correct Pi = 3.1446, doesn't even have a university degree and only talent is cutting round wooden disks, making pretty drawing and has above average coloring skills, when Billy Meier makes it perfectly clear the true and correct Pi is unknown.
Michael Horn and Christian Frehner believed the Pi = 3.1446 nonsense because they are unqualified to understand the mathematics of what they're supporting - like the blind leading the blind. They took a concept that there is an error in Pi, which Billy states, and blew it way out of proportion and ASSUMED and promoted the true and correct Pi = 3.1446 something Billy nor Ptaah nor any Plejaren have EVER stated is correct.
There are a number of not very intelligent folks within this community unfortunately but the Pi = 3.1446 nonsense needs to be purged before Apophis becomes daily news in the media and we can't have folks within the FIGU Community looking like fools promoting Pi = 3.1446. That would be terrible as it makes the FIGU Mission look like a bunch of idiots.
