Answer:

$768,000\pi\ in^(3)$

Explanation:

we know that

The volume of a cylinder (water pipe) is equal to

$V=\pi r^(2)L$

In this problem we have

$r=8/2=4\ in$ -----> the radius is half the diameter

$L=4,000\ ft$ ----> convert to inches

$L=4,000*12=48,000\ in$

$V=\pi (4^(2)48,000)=768,000\pi\ in^(3)$
