A sphere has a radius of 3 cm. What is the volume of the sphere?

Solution:

We know that the volume of the sphere can be found by using radius or diameter that is, diameter is twice the radius (d = 2r )

The formula for the volume of a sphere in terms of radius is

V = (4/3) π r³

Here the radius of the sphere is 3cm ( given )

So lets substitute the given value of r in the above formula

V = (4/3) π (3)³ = (4/3) π 27 = 36π.

And the value of π is 3.14

V = 113.04 cm³

Therefore, the volume of the sphere is 113.04 cm³.

A sphere has a radius of 3 cm. What is the volume of the sphere?

Summary:

A sphere has a radius of 3 cm. The volume of the sphere is 113.04 cm³.
