Distance between circumcenter and orthocenter ?

The distance between circum centre and orthocenter of the triangle whose vertices are (0,0),(6,8) and (-4,3) is

A triangle are (6,0).(0, 6) and (6,6) . If distance between circumcentre and orthocenter and distance between circumcentre and centroid are lambda and u unit respectively, then (lambda, u) lies on:

A triangle are (6,0).(0,6) and (6,6). If distance between circumcentre and orthocenter and distance between circumcentre and centroid are lambda and u unit respectively,then (lambda,u) lies on:

The distance between the circumcentre and orthocenter of a Delta ABC is R sqrt(1-lambda cos A*cos B*cos C), then lambda=

Given an isoceles triangle with equal side of length b and angle alpha lt pi//4 , then the distance between circumcenter O and incenter I is
