The volume of a sphere is 4/3 * pi * r^3
A hemisphere is half of that

Pretend it's a sphere. Calculate the volume of a sphere with that same radius (radius of a sphere and of a hemisphere are the same).
Then divide by two.

The volume of an entire sphere is defined as follows:
Volume = V = (4 * pi * r^3) / 3
V = (4 * 3.14 * 5^3) / 3
V = 1570.796/3
V = 523.5988
For a HEMI-sphere, its half of that or 261.7994 cubic units
For reference, the surface area of an entire sphere is 4 * pi * r^2 (square units)

Volume = 1/2 of sphere
Vsphere = 4/3 * pi * r^3
so... V = 4/6 * pi * r^3
