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 be
2r...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 be
C = 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 be

Volume of a sphere = 4/3*pi*radius3 and legend has it that Archimedes was having a bath when he discovered the formula
It is the formula for finding the surface area of a sphere which is 4*pi*radius2
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Add the lengths of each side together to get the perimeter.
Just insert the radius into the formula for the volume a sphere, and do the calculations. The formula is: V = (4/3) pi radius3
