▸Circumradius R = 4.0415 cm for this scalene triangle.
- The circumradius is 4.0415 cm, so the circumcircle has a diameter of 8.0829 cm.
- The circumcircle area is 2.96x the triangle area - for any triangle this ratio is always at least pi/3 (about 1.047) and equals exactly 3.628 for an equilateral triangle.
- The incircle radius (inradius) is 1.7321 cm. For this scalene triangle, R/r = 2.333 (the minimum possible is 2, for equilateral triangles - Euler's inequality).
- The Euler distance between circumcenter and incenter is 1.5275 cm.
Next stepFor a scalene triangle, the circumcenter lies inside the triangle if all angles are acute, and outside if one angle is obtuse.
