The radius of a sphere is 3 inches. Which represents the volume of the sphere?
12π cubic inches, 36π cubic inches, 64π cubic inches, 81π cubic inches

Solution:

Given, the radius of a sphere = 3 inches.

We have to find the volume of the sphere.

Volume of the sphere = 4/3(πr³)

So, volume = 4/3(π(3)³)

= 4/3(27π)

= 4(9π)

= 36π

Therefore, volume of the sphere is 36π cubic inches.

Example:

The radius of a sphere is 2 inches. Which represents the volume of the sphere?

Solution:

Given, the radius of a sphere = 2 inches.

We have to find the volume of the sphere.

Volume of the sphere = 4/3(πr³)

So, volume = 4/3(π(2)³)

= 4/3(8π)

= 32π/3

Therefore, volume of the sphere is 32π/3 cubic inches.

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

Summary:

The diameter of a sphere is 3 inches. The volume of the sphere is 36π cubic inches.
