No, the first one is (x - 2)2 + (y - (-8))2 = 92, or (x - 2)2 + (y + 8)2 = 92

You should rely on the formula of a circle that looks as $$(x - x_{center})^2 + (y - y_{center})^2 = R^2$$,

where the center of a circle has coordinates $$(x_{center}; y_{center})$$, any point of the coordinate system has coordinate $$(x ; y)$$$$R$$ is radius. Good luck!

So for example the first one? would be

(2-2)^2+(-8- -8)^2=9^2 ?????
