The quickest way would be to actually measure it!
Another way is to find how high/wide the ball is. This has to be done very accurately. Yoy could use parallel wooden boards (be careful not to squash the ball!
The multiply the width/height of the ball by 3.14159265 (Pi).
The formula is Pi x d (diameter) = circumference. A ball that is 30 cms in diameter will have a circumference of 94.248 cms.

What is the diameter of a circle with a circumference of 49 centimeters?
Oh, dude, math time! So, the formula for finding the diameter of a circle from the circumference is dividing the circumference by π (pi). In this case, 49 divided by π is approximately 15.57 centimeters. So, the diameter of the circle is around 15.57 centimeters. Easy peasy, right?
