Distance Between Circumcenter and incenter

What is the Distance between circumcenter and orthocenter?

What is the Distance between Incenter and excenter?

Prove that the distance between the circumcenter and the incenter of triangle ABC is sqrt(R^(2)-2Rr)

In A B C ,l e tR=c i r c u m r a d i u s ,r=in r a d i u sdot If r is the distance between the circumcenter and the incenter, the ratio R/r is equal to sqrt(2)-1 (b) sqrt(3)-1 sqrt(2)+1 (d) sqrt(3)+1

The distance between the circumcenter and the orthocentre of the triangle whose vertices are (0,0),(6,8), and (-4,3) is L. Then the value of (2)/(sqrt(5))L is

If veca, vecb and vecc are position vectors of A,B, and C respectively of DeltaABC and if|veca-vecb|=4,|vecb-vec(c)|=2, |vecc-veca|=3 , then the distance between the centroid and incenter of triangleABC is
