How do you find the circumradius of a triangle?

Back

The circumradius (R) can be found using the formula R = (abc)/(4K), where a, b, and c are the lengths of the sides of the triangle and K is the area of the triangle.

What is the relationship between the circumcenter and the circumradius?

Back

The circumcenter is the center of the circumcircle, which is the circle that passes through all three vertices of the triangle. The circumradius is the radius of this circumcircle.
