This manual screenshot is from the old wiki and is valid for 2.0 versions, as noted there on the top of the page.
Menus and tools were revamped with LibreCAD 2.1 and the manual for 2.1 and 2.2 is linked there too.

I didn't check, but possibly there was a concentric tool in 2.0, which was moved/renamed to offset in 2.1.
As already mentioned above, the Line tool Parallel or the Modify tool Offset are both usable for concentric circles.
I prefer the Parallel tool, it is more powerful and easier to use.
For the distance, you may not have recognized the tool option bar yet, which appear when the tool is active.
You find it on top of the drawing area, right beside the drawing style options.
If the tool option bar was disabled by accident, you can enable it in the Widgets/Toolbars menu again.
