Question

The diameter of a cylindrical construction pipe is 4ft If the pipe is 17ft long, what is its volume? Use the value 3.14 for /pi, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.

Answer 1

213.52 cubic ft

Explanation:

Diameter of pipe = 4ft

radius for circle is half of diameter

thus radius of pipe = 1/2 of 4ft = 2 ft

length of pipe = 17 feet

volume of cylinder is given by
`\pi r^2l`

where r is the radius and l is the length of cylinder

.

thus volume of pipe is calculated below using above values

`volume \ of \ pipe = \pi r^2l\\volume \ of \ pipe = \3.14* 2^2*17 \\volume \ of \ pipe = 213.52`

volume of pipe is 213.52 cubic ft.
