@A Former Brilliant Member – I actually saw that pic along with some other maths memes, and I think I know whats wrong with it. Obviously, the square will never actually become the circle, It'll be just finely spaced jagged lines around a circle with the perimeter of each 'triangular' element becoming smaller as we continue our iteration. But this will also increase the number of such triangles, thus keeping the level of inaccuracy intact!
@A Former Brilliant Member – No I don't see it, what's wrong with his solution?

@Baby Googa – The circumference is not equal to pi, since pi is the ratio of the circumference to the diameter.
Also, the perimeter of a a figure will be different once you "change" the figure. The perimeter of the "changed" square (which is shown to be a circle) typically is not the same as the perimeter of the original square, so you technically can't use the original perimeter as a circumference that you will use in a ratio with the diamater to find pi.

@Iñigo Reyes – yes the circumference is equal to pi since the diameter is 1. no the perimeter could be the same
That's just ... bad image software that you have
This reminds me of coastline paradox
and this was supposed to be an educational website
This was truly great!!

So still it's inverted ? Hard luck :P
Stupid... the answer will be pi=3.14159
Hahahhahahahah -_-
What is wrong is that when you subtract, you shouldn't subtract squares, you should subtract that "circle-like-hypotenuse right angled triangle", not a complete square. The question reminds me of somthing that said( how does the plane fly?) and the answer was (it flies fast). It's nice, but doesn't deserve to be a math question
mmm... i'd rather be studying microeconomics...

What is the logical fallacy in that?

We're still measuring the perimeter of the zig zag lines of the squares, and not the perimeter of the circle.
You are G R E A T ! !
Its in correct when you cannot remove the corners to infinite.. if you do so you will be cutting /crossing the perimeter of the circle...
I am not a math genius I got pi as my answer. How the hell could pi be 4 and not 3.14159?

Calm down its a troll contest :)
This is part of a troll competition. The correct answer is pi, but he jokingly "proved" pi to be equal to 4.
