Question

if you have installed 4000 linear feet of 8 inch water pipe how much will it hold when full? (answe is 10,543) i need help writing it out​

Answer 1

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

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

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