Best ResponseYou've already chosen the best response.1your equation is so far: (x5)^2+(y+4)^2=r^2 now you are also given a point (x,y) that is on the circle this will allow you to solve for r

Best ResponseYou've already chosen the best response.1That point being (3,2) so replace x with 3 and y with 2 and solve for r

Best ResponseYou've already chosen the best response.1\[(35)^2+(2+4)^2=r^2 \\ (8)^2+(6)^2=r^2\] did you get this far?

Best ResponseYou've already chosen the best response.1and so you winded up with 64+36=r^2 right?

Best ResponseYou've already chosen the best response.1well 64+36 should be 100

Best ResponseYou've already chosen the best response.1you are really done because the standard form of a circle is (xh)^2+(yk)^2=r^2 where we needed values h,k , and r^2 we just found r^2 and we were given h and k
