The equation of a circle can be written (x-h)2 + (y-k)2 = r2 where h is the x coordinate of the circle's center, k is the y coordinate of the circle's center, and r is the radius of the circle.
Therefore, for a circle with center of (2,3) and radius 10 units, the equation would be:
(x-2)2 + (y-3)2 = 100
In this problem, h = 2, k = 3, and r = 10
