Question

The diameter of a cylindrical construction pipe is 6 ft. If the pipe is 34 ft long, what is its volume?

Answer 1

Given:

The diameter of the cylindrical pipe = 6ft.

Height of the pipe = 34 ft

To find:

The volume of the pipe.

Solution:

We have,

Diameter of cylinder = 6 ft

Radius of cylinder $=\dfrac{6}{2}=3$ ft

Height of the pipe = 34 ft

Volume of a cylinder is

$V=\pi r^2h$

Where, r is the radius and h is the height.

Putting r=3 and h=34, we get

$V=\pi (3)^2(34)$

$V=\pi (9)(34)$

$V=306\pi$

$V=306(3.14)$

$V=960.84$

Therefore, the volume of the cylindrical pipe is $306\pi \approx 960.84$ cubic ft.
