Jenni plots her house and yard on a computer. she determines that the circle that defines the part of the front yard that gets watered by the sprinkler is (x−9)^2+(y+11)^2=16.

what is the diameter, in meters, of the circular area that gets watered by the sprinkler?

4 m

8 m

16 m

32 m

B) 8 m

Step-by-step explanation:

The standard form a circle : (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.

Given: (x−9)^2+(y+11)^2=16.

Comparing the given equation with the standard form, we get

Center = (h, k) = (9, -11)

Radius = r^2 = 16

Now let's find r taking the square root.

r = 4

Diameter = 2 * radius

Diameter = 2*4 = 8 meters

B) 8 m

Hope this will helpful.

Thank you.

the answer is 0.3175 hope that you ^w^
