Answer:
A. 2.9π(9²)
Step-by-step explanation:
You are expected to know that the area of a circle is given by the formula ...
A = πr²
and that r in the formula represents the radius of the circle, half the diameter.
The area of the circular base of the cylinder is the area of a circle with a radius of 9 feet. It will be ...
A = π(9²)
When that is multiplied by the height of the cylinder to find its volume, you have ...
V = Bh
V = (π(9²))(2.9)
This can be rearranged to match the form in answer choice A:
2.9π(9)²
Well to find the range, you need to take the highest number and subtract the lowest from it:
3 - -97
3 + 97
100
Range is always positive!
I hope this helps!

Answer:
C. The graph of the function starts high and ends low
Step-by-step explanation:
For 
, as 
approaches negative infinity, 
approaches infinity, and as approaches infinity, approaches negative infinity.
Thus, we have:
This corresponds with answer choice C. The graph of the function starts high and ends low.
