Question

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 lateral surface area formula

The lateral surface area of a cylinder is $A = 2\pi rh$, where $r$ is radius, $h$ is height.

Step2: Substitute given values

Substitute $r=4$, $h=30$, $\pi=3.14$:
$A = 2 \times 3.14 \times 4 \times 30$

Step3: Calculate step-by-step

First compute $2 \times 3.14 = 6.28$, then $6.28 \times 4 = 25.12$, finally $25.12 \times 30 = 753.6$

Answer:

753.6 square feet
