Question

Find the coordinates of the centre of a circle passing through the points A(3, 5) B(- 1, 1) and C(3, -3). Also find the radius of the circle.

Answer 1

Answer:

OA=OB=OC(Radii of the circle)

Hence, distance is same, we considered the co ordinates of O to be x and y, and equations, we found out that x is - 2 and y is - 4,then we took out the distance i.e the radius of the circle which came out to be root 106 units.
