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: [tex]A= \pi r^2[/tex]
- We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula: [tex]r = \frac{d}{2}[/tex]
- Plug in numbers: [tex]r=\frac{15}{2}[/tex] ≈ [tex]7.5[/tex]
- Use the Area formula now that you have radius: [tex]A=\pi 7.5^2[/tex]
- Solve and get = [tex]a = 176.71458676[/tex]
- 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.
