Answer:

x=3  and x=-5

Step-by-step explanation:

To find the x intercepts set y =0 and solve for x

0 = x^2+2x-15

Factor

What two numbers multiply to -15 and add to 2

5*-3 = -15

5+-3 =2

0 = (x+5) (x-3)

Using the zero product property

x+5=0   x-3 =0

x=-5      x=3

Okay. Let’s begin!

I order to solve this problem we must u do it and redo it. We have to find the diameter and the radius

Step one: 15 divided by 3.14 (PI) which is 4.77707006. That’s the diameter. Now divide that by two for the radius which is 2.38853503

Step two: find the area

Formula: PI(r)^2

Step three: solve for the area

3.14(2.38853503)^2

Step four: answer

Your answer is.....

17.9140127. Or if ur rounding:

18.

I hope this helped!
