Charlie used a coupon and pos 9.99 for a pizza and it normally costs 15.99 14* the percentage of the change would be %1.28
You can solve this problem through factoring.
First, you have the equation,

Then, you can factor the numerator.

You can cancel out the x-6 in both the numerator and the denominator because they would equal to just 1.
You are left with 
The function is removable noncontinuous at x=6 because if you plug in 6 in x-6, your denominator would be undefined.

Answer:
1583.4 ft³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
The radius is half the diameter, so is (12 ft)/2 = 6 ft. Then the volume is ...
V = π(6 ft)²(14 ft) ≈ 1583.4 ft³

<em>Additional comment</em>
The number shown in the problem statement answer box is the number you would get using the diameter in the above formula instead of the radius.
