Question

the radius of a cylindrical construction pipe is 2ft. if the pipe is 22ft 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: Recall the formula for the volume of a cylinder

The formula for the volume of a cylinder is \(V=\pi r^{2}h\), where \(r\) is the radius and \(h\) is the height (or length in this case).

Step2: Substitute the given values into the formula

Given \(r = 2\) ft and \(h=22\) ft, and \(\pi = 3.14\).

Step3: Perform the multiplications

First, \(3.14\times4 = 12.56\). Then \(12.56\times22=276.32\)

Answer:

\(276\mathrm{ft}^{3}\)
