Question

A pipe has a diameter of 2.5 inches and a length of 15 inches. The plumber also wants to know how much water can flow through his pipe at one time. To the nearest tenth, what is the volume of the pipe?

Answer 1

volume is approximately 73.6 to the nearest tenth

Explanation:

The volume of a pipe is volume = π * radius² * length

diameter = 2.5

radius = 2.5/2 = 1.25 inches

volume = π * 1.25² * 15

volume = π * 1.5625 * 15

volume = π * 23.4

which is approximately 73.6 to the nearest tenth
