Question

An ice cream company wants to package a pint of ice cream in a circular cylinder that is 4 inches high. A pint is 16 fluid ounces and 1 fluid ounce is 1.8 cubic inches. What does the radius of the base circle Have to be?

Answer 1

The radius of the base circle has to be 1.51 inches

Explanation:

1. Let's review the information given to us to answer the question correctly:

Height of the ice cream package = 4 inches

Volume of the ice cream package = 1 pint = 16 fluid ounces

2. What does the radius of the base circle have to be?

Let's calculate the volume of the ice cream package, as follows:

16 fluid ounces = 16 * 1.8 inches³

Volume = 28.8 inches³

Let's recall the formula of the volume of a cylinder:

Volume = π * r² * h

Replacing with the values we have:

28.8 = 3.1416 * r² * 4

28.8 = 12.57 r²

r² = 28.8/12.57

r² = 2.29

√ r² = √2.29

r = 1.51 inches
