A concrete pillar has the shape of a cylinder. It has a radius of 3 m and a height of 7 m. If concrete cost $116 per cubic meter how much did the concrete cost for the pillar?

Answer: the concrete cost for the pillar is $22947.12

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

The cylindrical concrete pillar has has a radius of 3 m and a height of 7 m. Therefore, the volume of concrete cylinder would be

Volume = 3.14 * 3² * 7 = 197.82 cubic meter

If concrete cost $116 per cubic meter, the cost of the concrete would be

116 * 197.82

= $22947.12
