Question

Electric utility poles in the form of right cylinders are made out of wood that costs $12.09 per cubic foot. Calculate the cost of a utility pole with a diameter of 1.5 ft and a height of 25 ft. Round your answer to the nearest cent.

Answer 1

Explanation:

Volume of a cylinder = pi r^2 h diameter =1.5 ft so r = .75 ft

pi * .75^2 * 25 = 44.18 ft^3

Find price (based on $ 12.09 /ft^3)

44.18 ft^3 * $ 12.09 /ft^3 = $ 534.12
