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 need to refinish the silo he will not be refinishing the top or bottom of the silo use 3.14 for pi
To find the surface area of the side of the silo, we need to find the lateral area of the cylinder.
The formula for the lateral area of a cylinder is given by 2πrh, where r is the radius of the base and h is the height of the cylinder.
In this case, the radius (r) of the silo is 4 feet and the height (h) is 30 feet.
Lateral area = 2 * 3.14 * 4 * 30
= 8 * 3.14 * 30
= 754.8 square feet
Therefore, 754.8 square feet of aluminum are needed to refinish the side of the silo.
