(x-5)^2 + (y+2)^2 = 16.

Step-by-step explanation:

Since the circle's radius is 4, we know the right side of the equation is 16.

Then, take the circle's center coordinate (5, -2) to fill the equation:

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

so (5,-2) is (h,k)

and (x-5)^2 + (y+2)^2 = 16.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
