Question

Electric utility poles in the form of right cylinders are made out of wood that costs

$15.45 per cubic foot. Calculate the cost of a utility pole with a diameter of 1 ft and a
height of 30 ft. Round your answer to the nearest cent.

Answer 1

Answer:$364

Explanation:

To find the number of cubic feet in this cylinder, we would need to find the volume by multiplying the height in feet of the cylinder by pi by the radius squared.

30 x pi x 0.5^2 = 23.56 cubic feet

since our height is given to us as 30, and the diameter is 1, we know our radius is 0.5.

After that, we simply multiply the charge per cubic foot ($15.45) by the number we got for volume (23.56)

$15.45 x 23.56 = $364.002 which rounded to the nearest cent = $364
