Question

A drum of oil has a height of 4 ft and a radius of 1.2 ft. The oil cost $22 per ft³. What is the cost to fill the drum of oil? Use 3.14 to approximate pi. Round your answer to the nearest penny. Enter your answer in the box.

Answer 1

Volume of a Cylinder (Drum) = πr²h

Substitute the known values,
v = 3.14 * (1.2)² * 4
v = 18.09 Ft³

Now, price for 1 Ft³ = $22
So, for 18.09 Ft³ would be: 22 * 18.09 = $397.9

In short, Your Answer would be: $397.9

Hope this helps!
