Question

what is the volume of this cylinder? round your answer to the nearest hundredth. 22 ft 12 ft cubic feet

Explanation:

Step1: Find the radius

The diameter is 22 ft, so the radius $r=\frac{22}{2}=11$ ft.

Step2: Use the volume formula

The volume formula for a cylinder is $V = \pi r^{2}h$. Substitute $r = 11$ ft and $h=12$ ft. So $V=\pi\times(11)^{2}\times12$.

Step3: Calculate the volume

$V=\pi\times121\times12 = 1452\pi$. Using $\pi\approx3.14159$, $V\approx1452\times3.14159 = 4561.69868$.

Step4: Round the answer

Rounding to the nearest hundredth, $V\approx4561.70$ cubic - feet.

Answer:

4561.70
