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 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 3.14 for pi and round your answer to the nearest tenth.(1 point)

that's wrong
that is wrong childdd
The silo can be thought of as a cylinder, with a curved surface area that needs to be refinished with aluminum.
The formula for the curved surface area of a cylinder is 2πrh, where r is the radius and h is the height.
Given that the radius is 4 feet and the height is 30 feet, we can plug these values into the formula:
Curved surface area = 2π(4)(30)
= 240π
≈ 754.4 square feet
Therefore, the farmer needs to purchase approximately 754.4 square feet of aluminum to refinish the side of the silo.
