R = 8
h = 15
a = r^2 * pi
a = 64pi = 201.06 sq.in.
201.06 * 15 = 3015.9 cubic inches.
Answer=15X
$45/3 hours = $15/hour
(b) To see how much Louis makes per hour, simply plug in 1 for the hours value x:
y = 12(1 hours)
y = $12/hour
Thus Carl makes more than Louis.
(c) The equation of Carl's dollars per hour is similar to Louis':
For this case we have the following equation:

By completing squares we have:
Step 1:
Add
on both sides:

Step 2:
We rewrite the equation:

Step 3:
We solve the equation:

Solutions:

Answer:
