Answer:
(x -9)^2 +(y -12)^2 = 225
Step-by-step explanation:
The equation of a circle with center (h, k) that passes through point (a, b) is ...
(x -h)^2 +(y -k)^2 = (a -h)^2 +(b -k)^2
For your given points, the equation is ...
(x -9)^2 +(y -12)^2 = (0 -9)^2 +(0 -12)^2 = 81 +144
(x -9)^2 +(y -12)^2 = 225
