Let's look at the first one, then you can practice the rest on your own. So, h(0) = - 2 because the number in h() is which number you search for on the bottom row. Then you look at the number above that bottom number, which, in this case is - 2, and that number is your answer.

Answer:

C. 176.6 Square feet (I think)

Step-by-step explanation:

I tried many different ways and got three of the answers above but I think this is the right one.

The equation to find area of a circular cone base: $A= \pi r^2$

We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula: $r = \frac{d}{2}$
Plug in numbers: $r=\frac{15}{2}$ ≈ $7.5$
Use the Area formula now that you have radius: $A=\pi 7.5^2$
Solve and get = $a = 176.71458676$
Looking at the options the closest one to our answer (off by one-tenth) is C.

Sorry if you get this wrong. I tried lol.
