The equation of the circle through three points online calculator


Online calculator which helps you calculate the equation of the circle at three given points and finding coordinates of the center point and the radius of the circle.
The equation of the circle is:
r2 = (x — h)2 + (y — k)2.
Where (h,k are the coordinates of the center of the circle), (x,y — coordinates of the points of a circle), (r — radius).
