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)
To find the surface area of the side of the silo, we need to find the lateral surface area of a cylinder. The formula for the lateral surface area of a cylinder is given by 2Ï€rh, where r is the radius of the base and h is the height of the cylinder.
Given that r = 4 feet and h = 30 feet, we can substitute these values into the formula to find the lateral surface area:
Lateral Surface Area = 2Ï€rh
= 2(3.14)(4)(30)
= 753.6 square feet
Therefore, the farmer needs to refinish approximately 753.6 square feet of aluminum.
