Every assumption you will read, or have read on this site of mine a­bout π has fi­nal­ly been prov­en cor­rect, thanks to the ge­o­met­ric de­vice called «Pi-drawer» that I de­signed to lit­er­al­ly extract from the cir­cle and per­form the ex­act cal­cu­la­tion of the re­al Pi con­stant, us­ing a 4th degree pol­y­no­mi­al al­ge­bra­ic e­qua­tion with ra­tion­al co­ef­fi­cients (yet declared in­ap­pli­ca­ble by π con­tor­tionists).
Note that the theorem, while ul­ti­mate­ly val­i­dating all my ar­gu­ments, was developed quite in­de­pend­ently from what I have for­mu­lat­ed in the var­i­ous articles on the golden section which, the more because it is its point of arrival and radix, cannot be adopted to demonstrate itself.
It is not based on personal formulas, but on objective and linear ge­o­me­tric and algebraic deductions, such that they cannot be questioned.
Alike we commonly use to define the golden ratio a+b÷a=a÷b (for me is much more in depth: 1=x+x×x), deriving it from a segment's partition, we will see how to represent ¼π as 1_/l² - l² = 1 deriving it from an effective circle partition.
To quickly discover how it was achieved, tap and follow the LEGENDA's flipping page (may not work on mobile devices).

π is indeed 3.14460… and no one will ever be able to deny it!

In a unit quadrant, you see a ¼ circle inscribed in a ¼ square. The ratio between the circle and the square can be de­duced, for ⅛ of both, from the curvature of one side EB in an arc AB. We only need to transfer the ex­act length of AB on EB to be able to measure it straight-line. HOW TO DO IT, in short

With l=AB=⅛ of a circle, an arc cb of radius 1/l will have length =1, so the extension of DE up to f on its tangent makes fb=cb. The segment fC in­ter­secting EB in e, will ensure eB=l from which Ce²=l²+1. cb also meets EB in e since the sin(eb) is =l, so as radius of cb, Ce =1/l extracts l. 1/l= √l²+1 1/l² = l²+1 l²= ½√5 -½ l is PLATINUM ¼ of actual π FOR A SLICE OF PIE
