# 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(πr^{3})

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(πr^{3})

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.
