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

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

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

A fair charges $7.25 for admission and $5.50 for a ride pass. Ten friends visited the fair. Not all of the friends purchased rid

kati45 [8]

You take
7.25 (10)+5.5p=105.5
72.5+5.5p=105.5
To make the equation easier multiply the whole equation by ten like this
(72.5+5.5p=105.5)10 that equals
725+55p=1055
Then subtract 725 to both sides
725+55p=1055
-725 -725
____ _____
55p=330
Then divide by 55 on both sides and that equals 6 so 6 people bought tickets
