To find the surface area of the side of the silo, we need to find the lateral area. The formula for the lateral area of a cylinder is given by L = 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 substitute these values into the formula:
L = 2(3.14)(4)(30)
L = 240(3.14)
L = 753.6
Therefore, the farmer needs to refinish approximately 753.6 square feet of aluminum.
