Using the volume of a cylinder, it is found that the approximate height of the container in inches is given by:
d. 15.48
<h3>What is the volume of a cylinder?</h3>
The volume of a cylinder of radius r and height h is given by:
In this problem, Sam pours 3 gallons of water into a cylindrical container, and it will be 90% full. Hence, the volume, in cubic feet, is:
The diameter of the container is 8 inches, hence the radius is of 4 inches = 0.3333 feet, considering a feet has 12 inches.
The height, in feet, will be given by:
Considering a feet has 12 inches, in inches, the height will be of:
1.2768 x 12 = 15.48
Hence option D is correct.
