GuDViN [60]

Answer:

768,000\pi\ in^{3}  

Step-by-step 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}
