Question

The radius of a sphere is 3 inches. Which represents the volume of the sphere?

Answer 1

Answer:

36π cubic inches

Step-by-step explanation:

Volume of sphere:

V = 4/3 πr^3

Given: r = 3 in.

Plug in

V = 4/3 π (3^3)

V = 4/3 π (27)

V = 36 π

Answer

36π cubic inches

Answer 2

Answer with explanation:

 Radius of the Sphere (r)= 3 inches

Volume of the sphere

                  $=\frac{4*\pi *r^3}{3}\\\\\rightarrow \frac{4*\pi *3^3}{3}\\\\\rightarrow 4*\pi *3^2\\\\=36\pi \text{Cubic inches}$
