Write the equation for a circle that satisfies the given conditions.
Alisiya [41]

The standard form of a circle is:

(x-a)^2+(y-b)^2=r^2

Your center is (-10,  -6) and your radius is 9

Plug them into the equation and you get

(x-(-10))+(y-(-6)) = 9^2

(x+10)^2 + (y+6)^2=81

The correct answer is D.
