Thanks banerjeea_98 you have the correct answer.
My math is a little rusty the eqn of the circle is X^2 + Y^2 = R^2 (R = Radius)
Is this the standard eqn of the circle irrespective if the center is origin (0, 0) or center is on any other quadrant e.g (2, 3) OR (-4,-6) The eqn is still the same, right ? Please clarify.
no generic eqn is (x-a)^2 + (y-b)^2 = r^2.....where r = radius and (a,b) is the center.
