A hemisphere is defined as a three-dimensional shape that is half of a sphere with exactly one flat side and a circular surface on the other side.

The volume of a sphere is evaluated by the formula

                                                      ,

where is the radius of the sphere.

Following the definition of the hemisphere, the volume is then calculated as

                                                      .

Therefore,

                                               .
