вычисление объёма полушария

1. A hemisphere is a 3D geometric shape that represents half of a sphere; it is obtained by cutting a sphere into two equal halves along its equator.

2. Hemisphere volume formula: Hemisphere volume = (2/3)πr³

(1) π is the mathematical constant pi, approximately equal to

(2) r is the radius of the sphere

3. Since a hemisphere is half of a sphere, the volume of a hemisphere is also half the volume of the entire sphere.
