Pi is an irrational number that is infinite, so any number sequence you can think of is also technically pi

Circumference of a circle can't be calculated without itself, as pi is made up of circumference only(π=C/D)

ELI5: Why is the area of a circle πr² ???
-
Since the number pi is infinite and irrational (meaning it doesn't repeat) then somewhere along that long strand of numbers is a sequence that, when converted to pixels, creates and image of yourself

ELI5: why would Pi not be a rational number? If the entire universe can be expressed in mathematical formulas, why would such an important constant be so random?
-
ELI5: Why is the value of pi 22/7 (or 3.141592654....)
-
Here is my proof that: inf) 2^n * sqrt(2-a_(n-1) (2)) = pi, where a_n (x) is defined recursively as a_n (x) = sqrt(x+a_(n-1) (x)), and a_0 (x) = 0. >>. I would very much like a critique of my proof :)
