Answer:
First, convert the hour to minutes.
1 hr = 60 mins
15 mins: 60 mins
1:4
the rate of change is -2 for every set shown in the chart on the right
so 6 to 7 would be -11 -2 = -13
7 to 8 would be -13-2 = -15
8 to 9 = -15-2 = -17
B is the answer
So,

Multiply both sides by 11.

Divide both sides by 7.
f = 1
Check.


This checks.
S = {1}
Answer:
<em>| In Terms of Pi π |
</em>
<em>V = 6000 π m3</em>
<em>-----------------------</em>
<em>or</em>
<em>V = 18840 m3</em>
<em>-----------------------</em>
<em>| In Terms of Pi π | </em>
<em>V = 168 π m</em>
<em>------------------------</em>
<em>or</em>
<em>V = 527.78756580309 m3</em>
