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

`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)`
