Question

A concrete pillar has the shape of a cylinder. It has a radius of 3 meters and a height of 5 meters. If concrete costs $96 per cubic meter, how much did the concrete cost for the pillar?

Answer 1

Total cost for pillar = $13,564.8

Explanation:

Given that:

radius r = 3 meters

height h = 5 meters

Volume of cylinder = pi r^2 h

By putting values:

Volume of cylinder = (3.14) (3)^2 (5)

Volume of cylinder = 141.3 cubic meter

As the concrete needed per cubic meter costs $96

So,

Total cost = $96 * 141.3 cubic meter

Total cost for pillar = $13,564.8
