A hemisphere is half a sphere. This suggests the following method: Step 1. Calculate the volume of a sphere that is as big as two of your hemispheres. Given a radius r, that volume is: 4/3 * pi * r^3 pi is approximately 3.1415927 r^3 means r*r*r (r cubed) Step 2. Divide answer of first step by 2 The volume of a sphere is given by V=4piR^3/3 +four thirds pi R cubed" where V= the volume and R is the radius. The volume of a hemisphere (half-sphere) is half of this volume: V=2piR^3/3
