Question

A cylinder shaped drum is used to store used motor oil. The drum has a height of 3 ft and a radius of 1.5 ft.

How many cubic feet of oil does the drum hold?

Answer 1

4.5 or 1637.272 Because you have to multiply the feet and the radius to get cubic feet and the width

Answer 2

21.2

Explanation:

The answer is 21.2 ft²To do this we need to calculate the volume of the cylinder shaped drum.The volume (V) of the cylinder with height h and radius r is:V = π r² hWe have:π = 3.14r = 1.5 fth = 3 ftTherefore:V = π r² hV = 3.14 * (1.5 ft)² * 3 ftV = 21.2 ft²
