Find the centre of a circle passing through the points (6,-6), (3,7) and (3,3).

If your question is"Find the centre of a circle passing through the points (6,-6), (3,-7) and (3,3)." than the solution is-

 

Let A (6, –6), B (3, –7) and C (3, 3) be the points on the circle and the centre of the circle be P (h, k).

∴ PA = PB = PC  (Radius of the circle)

 

Thus, the centre of the circle is (3, –2).
