The compound inequality that gives the normal range for the pH values of lemon juice is given by:
A compound inequality is modeled by:
Which means that x is greater than a and less than b. In this problem, the pH is greater than 1.5 and less than 4, hence the inequality is given by:

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
