Answer:
[tex](x +3)^2 + (y - 7)^2 = 3^2[/tex]
Step-by-step explanation:
Well, the center origin of the circle is given (h,k) = (-3,7).
We have to find our radius as they gave us a point. from origin to the edge of the circle.
Using the formula: (x - h)^2 + (y - k)^2 = r^2
Plug in our (h,k) = (-3,7) and (x,y) = (0,7) to solve for radius.
(x - h)^2 + (y - k)^2 = r^2
(0 - (-3))^2 + (7 - (7)^2 = r^2
(3)^2 + (0)^2 = r^2
9 = r^2
r^2 = 9
r = 3
