Write the standard equation of the circle in the graph.
A. (x + 3)squared + (y  2)squared = 9
B. (x  3)squared + (y + 2)squared = 9
C. (x  3)squared + (y + 2)squared = 18
D. (x + 3)squared + (y  2)squared = 18
Help please! :)

Best ResponseYou've already chosen the best response.3the circle centre appears to be (3, 2) and the radius is r = 3 so the general form of a circle is \[(x  h)^2 + (y  k)^2 = r^2\] the centre is (h, k) and r is the radius just substitute the information for the centre and radius into the general equation.
