Question

the diameter of a cylindrical construction pipe is 4 ft. if the pipe is 16 ft long, what is its volume? use the value 3.14 for π, and round your answer to the nearest whole number. be sure to include the correct unit in your answer.

Explanation:

Step1: Find the radius

$r=\frac{d}{2}=\frac{4}{2}=2$ ft

Step2: Calculate the volume

$V = \pi r^{2}h=3.14\times2^{2}\times16 = 200.96$ ft³

Step3: Round to nearest whole number

$V\approx201$ ft³

Answer:

201 ft³
