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?

Use 3.14 to approximate pi.

Enter your answer as a decimal rounded to the nearest hundredth in the box.

Answer 1

Answer:The answer is 21.2 ft²

Step-by-step explanation: To 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 h

We have:

π = 3.14

r = 1.5 ft

h = 3 ft

Therefore:

V = π r² h

V = 3.14 * (1.5 ft)² * 3 ft

V = 21.2 ft²

Answer 2

The answer is 21.2 ft²

To 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 h

We have:
π = 3.14
r = 1.5 ft
h = 3 ft

Therefore:
V = π r² h
V = 3.14 * (1.5 ft)² * 3 ft
V = 21.2 ft²
