How do i find the diameter of a ping pong ball PS im only 13 don't write complicated answers?

Answer 1

1. take some string and wrap it once around the ping pong ball, make sure the string goes around the middle of the ball. pinch or mark the string where it touches the beginning of the string

2. now measure how long that segment of string is, this gives you the circumference of the ping pong ball

3. the formula to get the diameter if you know the circumference is

circumference / pi = diameter

so divide the length of the string by 3.14 and you have your diameter.

Easy as pie (ha ha)
