Answer:

4 ft³

Explanation:

From the question;

We are required to determine the volume of the air in the beach ball;

We need to know that the volume of the air is the same as the volume of the beach ball.
The ball is in the shape of a sphere

Volume of sphere=(4)/(3)pi*r^3

Radius = 12 inches

But, 1 ft = 12 inches

Thus, radius = 1 ft

Therefore;

Taking pi as 3.142

Volume = 4/3 × 3.142 × 1³

= 4.189 ft³

= 4 ft³ (nearest cubic foot)

Therefore, the volume of the air in the beach ball is 4 ft³
