The sides of Traingle ABC have lengths sqrt10, sqrt10, and 2. What is the circumradius of Traingle ABC?

Circumradius

The circumcircle of a triangle is a circle that passes through all of the triangle's vertices, and the circumradius of a triangle is the radius of the triangle's circumcircle. Circumcenter (center of circumcircle) is the point where the perpendicular bisectors of a triangle intersect.

R = { a b c } / { 4 r s } = { 3.16 * 3.16 * 2 } / { 4 * 0.721 * 4.162 } =** 1.667**, where r =inradius, s =semiperimeter.
