The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?

soldier1979 [14.2K]

Answer:

32 $\pi$ /3 cm³

Step-by-step explanation:

If the diameter is 4 cm, then the radius is 2 cm.

Use the sphere volume formula:

V = 4/3 $\pi$ r³

Plug in the radius and solve:

V = 4/3 $\pi$ (2)³

V = 4/3 $\pi$ (8)

V = 32 $\pi$ /3

So, the volume of the sphere is 32 $\pi$ /3 cm³
