What is the volume of a sphere with radius 3 (in terms of pi)?

Explanation:
Volume of a sphere is found with V = 4/3 π r^3. If the radius is 3, then V = 4/3 × π × 27 = 36π. So the volume in terms of π is 36π, which matches the correct option. The other numbers don’t come from this radius—changing r would change r^3 and thus the final coefficient of π.
