I don't know of a Circle/Concentric option and can't find anything about it in the manual.Where have you seen that? Or is it an option you are familiar with from an other CAD system?
You can edit the radius of a circle with Modify - Properties.
Or if you mean to get a circle with a certain distance around an existing one you can use Modify - Offset or Line - Parallel.
