Radius of the circumcircle of a triangle


The radius of the circle on which lie a set of points is, by definition, the radius of the circumcircle of any triangle with vertices at any three of those points. If the pairwise distances among three of the points are a, b, and c, then the circle’s radius can be calculated by the sides a,b and c of the triangle.
