The beach ball can hold 37.15 cubic feet of air
<u>Solution:</u>
Given that the beach ball has a diameter of 4.14 feet
We are asked to find how much air can fill the ball. This means that we have to find the volume of the ball
<em><u>Finding volume of ball:</u></em>
Given diameter = 4.14 feet
We know that radius is half of diameter


Since ball is a sphere, Volume of sphere is given as:

By substituting the value of radius we get,

Hence the beach ball can hold 37.15 cubic feet of air
