The equation to find area of a circular cone base: 
- We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula:

- Plug in numbers:
≈ 
- Use the Area formula now that you have radius:

- Solve and get =

- 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.
Answer:
See below.
Step-by-step explanation:
Multiplying terms with exponents make the exponents add together.
13.) x² · x⁵ = x⁷
14.) b⁵ · b³ = b⁸
15.) y⁴ · y⁷ = y¹¹
16.) m⁴ · m¹ = m⁵
We can't tell, because you won't let us SEE
the electric meter shown in the exam figure.
-9 because 2+7=9 so the negative part oh then must be -9
