Answer:

(x+7)^2 + (y - 4)^2 = 81. This matches

Answer Choice D.

Step-by-step explanation

Apply the standard equation of a circle with

center at (h, k) and radius r:

(x - h)^2 + (y - k)^2 = r^2

Here (h, k) is (-7, 4) and r is 18/2 or 9, and so the desired equation is

(x+7)^2 + (y - 4)^2 = 81. This matches Answer Choice D.
