A sphere has radius 1. What is its volume in terms of π?

Explanation:
The main concept is that the volume of a sphere depends on its radius cubed. The volume is given by V = (4/3) π r^3, since expanding in all three dimensions scales volume with the cube of the radius. With radius 1, substitute to get V = (4/3) π (1)^3 = 4/3 π. Therefore, the volume in terms of π is 4/3 π.
