Question

The diameter of a cylindrical construction pipe is 6ft. If the pipe is 32 long, what is its volume?

Use the value 3.14 for pie , and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.

Answer 1

`V_(pipe) \approx 904 \: {ft}^(3)`

Explanation:

Diameter of the pipe = 6 ft

Therefore, radius (r) = 6/2 = 3 ft

Height of pipe (h) = 32 ft

Since, pipe is cylindrical in shape.

`\therefore \: V_(pipe) =\pi {r}^(2) h \\ \\ \therefore \: V_(pipe) =3.14 {(3)}^(2) (32)\\ \\ \therefore \: V_(pipe) =3.14 {(3)}^(2) (32) \\ \\ \therefore \: V_(pipe) = 904.32 \\ \\ \therefore \: V_(pipe) \approx 904 \: {ft}^(3)`

Hence, the volume of pipe in nearest whole number is 904 cubic feet.
