The formula for the volume of a sphere is


V=(4\pi)/(3)r^3

where r represents the radius of the sphere.

A hemisphere is half of a sphere, therefore, it has half the volume of a sphere. A formula for the volume of a hemisphere is half the volume of a sphere, which is


(V)/(2)=(1)/(2)*(4)/(3)\pi r^3=(2)/(3)\pi r^3

The volume of a hemisphere is


V=(2)/(3)\pi r^3
