Question

The diameter of a cylindrical construction pipe is 6 ft, and the length is 29 ft.a) Find the exact volume of the pipe. Write you answer in terms of π.b) Using a calculator, approximate the volume of the pipe.To do the approximation, use your answer to part (a) and the π button on the calculator. Round your answer to the nearest 100th.

Answer 1

We get that the radius is 3 ft and the length is 29 ft so the volume is

$V=\pi\cdot3^2\cdot29=261\pi^{}$

the approximate value is:

$819.96ft^3$
