the radius of a cylindrical construction pipe is 2 ft, and its length is 21 ft. find the volume of the pipe write your answer in terms of pi also round my answer to neadzt hunddeth

Respuesta :

Okay, here we have this:

We need to calculate the volume of a cylinder with 2 ft of radius and 21 ft of length, so let's replace in the following formula:

V=πhr²

V=π(21 ft)(2 ft)²

V=84π ft³

Here we obtain that the volume in terms of pi is 84π ft³, no let's round to the nearest hundredth:

84π ft³≈263.89 ft³.
