Question

What is the approximate sum of the radii of the circumcircle and incircle?

Answer 1

Circumcircle --

The circumcircle is a triangle's circumscribed circle, i.e., the unique circle that passes through each of the triangle's three vertices. The center of the circumcircle is called the circumcenter, and the circle's radius is called the circumradius. ... The polar triangle of the circumcircle is the tangential triangle.

Answer 2

In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. Center of this circle is called the circumcenter and its radius is called the circumradius. A polygon that has a circumscribed circle is called a cyclic polygon.
