rabbit and hamster ball

Question
is it okay for my dwarf rabbit to runn around in one of those hamster balls?

Answer
Those aren't really designed for rabbits, rabbits do much better running around on the floor.  Hamsters don't mind running in circles constantly, but rabbits get tired of it very quickly and then he'll be looking for a way out.  He may feel confined and hurt himself trying to get out, so I just wouldn't try it in the first place.
