What is the formula for finding perimeter of sphere?

A sphere does not have a perimeter. It can have a diameter a circumference or a surface area (or volume but that isn't discussed here.The diameter of a sphere is two times the radius (r): so the formula would be2r...or...2 x rThe circumference (C) of a sphere is equal to 6.2832 times the Radius, where 6.2832 is twice Pi (): so the formula would beC = 2r...or...C = 2 x x rThe area of a sphere is equal to the Square of the Radius of the sphere multiplied by 12.566 (4 times ): so the formula would be4 * * R * R

How do you Calculate circumference of a ball?

To calculate the circumference of a ball (which is a sphere), you use the formula for the circumference of a circle, ( C = 2\pi r ), where ( r ) is the radius of the sphere. If you have the diameter ( d ) instead, you can use the formula ( C = \pi d ), since the diameter is twice the radius (( d = 2r )). Simply plug in the radius or diameter into the appropriate formula to find the circumference.
