we know that
The volume of cylinder is equal to

we have

substitute

simplify
Remember that
A sphere and a cylinder have the same radius and height
so
The height of cylinder is equal to the diameter of sphere
h=2r
substitute
-----> equation A
The volume of the sphere is equal to

substitute equation A in the formula of the volume of sphere
