If the displacement of a body is zero,is it necessary that the distance covered by it is also zero

If the object is moving in a circular path, let us assume it is started from a point and after one complete revolution
it reaches the same point. In this case displacement is zero but distance covered is 2πR, where R is the radius of circular path.
 
If the object started from a point , travels some distance and coming back to same point .
In this case also displacement is zero but distance covered is not zero
