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
4 * * R * R

How Archimedes found the formula for finding the volume of the sphere?
Volume of a sphere = 4/3*pi*radius3 and legend has it that Archimedes was having a bath when he discovered the formula
What is 4 pi r squared?
It is the formula for finding the surface area of a sphere which is 4*pi*radius2
How do you find the surface area of a sphere when its volume is 523.5987756 cubic cm?
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.
What is the formula for the perimeter of a equilateral triangle?
Add the lengths of each side together to get the perimeter.
What is the volume of a sphere with a radius of 15 units?
Just insert the radius into the formula for the volume a sphere, and do the calculations. The formula is: V = (4/3) pi radius3
