Answer 1

what are th points?

Answer 2

take any general points....Say (x1,y1);(x2,y2);(x3,y3)

Answer 3

can we use the general equation of a circle and solve for the constants?

Answer 4

hmm doesnt look simple. maybe there's a geometric argument

Answer 5

it would work, we get three equations in a, b, r

Answer 6

thanx man..!!!

Answer 7

that would obviously work....right now am not solving it for a general case....i just wanted the method in which already helped me out.....i can now solve it for any particular case...

Answer 8

awesome
