Vol = 4/3*pi*r3 so given the volume, you can calculate the radius. Height of sphere = 2*radius.
The volume of a sphere is 4/3 Pi x radius cubed. So given V you multiply the volume by 3/4 and divide by Pi, then take the cube root of that entire quantity and you have the radius.
A sphere
Because when working out volumes the answer is given in cubic units and the radius in the formula for finding the volume of a sphere is cubed: Volume of a sphere in cubic units = 4/3*pi*radius3
