Question

the diameter of a cylindrical construction pipe is 4 ft. if the pipe is 19 ft long, what s it’s volume?

Answer 1

76
`\pi` or 238.76
`units^(3)`

Explanation:

The volume of a cylinder is V =
`\pi r^(2) h`

Here the radius is r =
`(1)/(2) d` =
`(1)/(2)(4)=2`

The height is given as 19 ft

Then plug in all the numbers into the equation

V =
`\pi (2^(2))(19) = 76\pi = 238.76 units^(3)`
