The surface area of the side of the silo can be found using the formula for the lateral surface area of a cylinder:
A = 2πrh
where A is the surface area, π is approximately 3.14, r is the radius, and h is the height.
The radius of the silo is 4 feet, so r = 4 feet.
The height of the silo is 30 feet, so h = 30 feet.
Plugging these values into the formula, we get:
A = 2(3.14)(4 feet)(30 feet)
A = 2(3.14)(120 square feet)
A = 753.6 square feet
Therefore, the farmer needs to refinish approximately 753.6 square feet of aluminum on the side of the silo. Rounding to the nearest tenth, the answer is 753.6 square feet.
A silo is a large cylinder container that holds hay. A farmer needs to refinish the side of the silk 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 answers to the nearest tenth.
