Question

What is the volume of a sphere with a radius of 3 inches?

12π cubic inches
24π cubic inches
36π cubic inches
48π cubic inches

Answer 1

36

Explanation:

Answer 2

Answer: The answer is (C) 36π cubic inches.

Step-by-step explanation: We are given to find the volume of a sphere with radius 3 inches.

We know that the volume of a sphere with radius 'r' units is given by

`V=(4)/(3)\pi r^3.`

Here, we have,

radius, r = 3 inches.

Therefore, the volume of the sphere is given by

`V\\\\=(4)/(3)\pi r^3\\\\=(4)/(3)\pi * 3^3\\\\=(4)/(3)\pi * 27\\\\=36\pi~\textup{cubic inches}.`

Thus, (C) is the correct option.
