proof that pie=22/7
Answers
The proof for Pi is quite long, but you can try an interactive way to find Pi.
You can use darts! I'm not kidding, that's literally it.
Youtubers named Veritasium and Physics Girl made a video about it, but let me share their equation.
You start by taking a square board and draw a circle of any dimension on it.
The area of a circle is PI * r * r, if r is the circle's radius. The area of a square is 2r * 2r, if r is 1/2 of the length of the square's side.
Hence your equation will be as follows :-
(the number of darts landed inside the circle/ the number of darts in total) * 4 = pi.
Veritasium and Physics Girl found the value to be around 3.139. With approximation and random throwing, you can approximate the answer to 3.14
It's a fun way and I'd recommend you can try this experiment out. Or you can watch Physics Girl's video about this.
