The diameter of a beach ball is 10 inches. how many cubic inches of air can the beach ball hold? use 3.14 for pi. round to the nearest tenth of a cubic inch.
recall the formula sphere=4/3 pir^3

Volume of sphere(V) is given by:

         ....[1]

where

r is the radius of the sphere.

As per the statement:

The diameter of a beach ball is 10 inches.

We know that:

Divide both sides by 2 we get;

or

r = 5  inches

Substitute in [1] we get;

Use

then;

Simplify:

⇒ V = 523.333332 cubic inches

Therefore, the volume of beach ball to the nearest tenth of a cubic is, 523.3 cubic inches
