Eli5: I always thought pi is 22/7, but recently i found out that 22/7 is a number that is pretty close to pi, not pi itself. Then how do mathematicians found more “pi” ?

As a side note, 22/7 is ok, but a much better approximation is 355/113. It’s not too hard to remember as you start with 3 (a very approximate pi) and then do double 5’s and double 1’s followed by the last 3.
