There is a cylinder, cone, and sphere with the same radius. The cone and cylinder have the same height with h=r. If the volume of the cone is 36 units cubed, what is the volume of the sphere?

If anyone even has a guess, can you please help me?

volume of cone is 1/3 πr^2 h. since h=r, v = 1/3 πr^3
The sphere has a volume of 4/3 πr^3, or 4 times the volume of the cone.
so, ...
Thank You SOOOOOOO Much!!!! :D
