surface area of cylinders practice
complete this assessment to review what youve learned. it will not count toward your grade.
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)

Explanation:

Step1: Recall the formula for lateral surface area of a cylinder

The formula for the lateral surface area (\(LSA\)) of a cylinder is \(LSA = 2\pi rh\), where \(r\) is the radius and \(h\) is the height.

Step2: Substitute the given values into the formula

Given \(r = 4\) feet, \(h=30\) feet, and \(\pi = 3.14\).
