The standard equation of a circle on a coordinate plane with center (h, k) and radius r is:
(x - h)^2 + (y - k)^2 = r^2
Substitute h = 3, k = -2, and r = 3 into the equation:
(x - 3)^2 + (y + 2)^2 = 3^2
(x - 3)^2 + (y + 2)^2 = 9
Therefore, the standard equation of the circle in the graph is (x - 3)^2 + (y + 2)^2 = 9.
