Given:

The area of the given sphere = 36π in²

To find the volume of the given sphere.

We need to find the radius first.

Formula

  • The area of a sphere [tex]A = 4\pi r^{2}[/tex]
  • The volume of the sphere [tex]V = \frac{4}{3} \pi r^{3}[/tex]

where, r be the radius of the sphere.

Now,

According to the problem,

[tex]4\pi r^{2} = 36\pi[/tex]

or,[tex]4r^{2} = 36\\[/tex] [ Eliminating π from both the side]

or, [tex]r^{2} = \frac{36}{4}[/tex]

or, [tex]r = \sqrt{9}[/tex]

or, [tex]r = 3[/tex]

So,

The radius of the sphere is 3 inches

Therefore,

The volume of the sphere is

[tex]V = \frac{4}{3} \pi (3)^{3}[/tex]

or, [tex]V = 36\pi[/tex]

Hence,

The volume of the sphere is 36π cube inches.
