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

  1. 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}
  2. Plug in numbers: r=\frac{15}{2} ≈ 7.5
  3. Use the Area formula now that you have radius: A=\pi 7.5^2
  4. Solve and get = a = 176.71458676
  5. 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.
