A silo is a large cylinder container that holds hay. A farmer needs To refinish the side of the silo with aluminum. The silo has a radius of 4 feet feet and a height of 30 feet how many square feet of aluminum does the farmer need to refinish the silo? He will not be refinishing the top or bottom of the silo. Use 3.144 pi and round your answer to the nearest 10th.

1 answer

To find the surface area of the cylindrical silo, we need to find the lateral surface area.

Lateral Surface Area = 2 * pi * radius * height
Lateral Surface Area = 2 * 3.144 * 4 * 30
Lateral Surface Area = 753.6 square feet

Therefore, the farmer will need 753.6 square feet of aluminum to refinish the side of the silo.
