rearrange into standard form : ax² + bx + c = 0 (a≠ 0)

2x² - 3x - 2 = 0

(x - 2)(2x + 1) = 0 ( equate each factor to zero and solve for x )

x - 2 = 0 ⇒ x = 2

2x + 1 = 0 ⇒ x = - 0.5

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.
