Formula for the volume of a sphere:

Formula for the surface area of a sphere:

the volume of a hemisphere is one-half the volume of a sphere with the same radius. The surface area of a hemisphere a matter of interpretation. Either it is half the surface area of a sphere with the same radius, or it is that same half sphere surface area PLUS the area of the circular base of the hemisphere, namely .
