Hold both shift and control when resizing to (a) scale from the centre,
and (b) scale proportionally (keep it circular).
You can also use Tile Clones, 1 row x 10 cols, -100% x-shift, -10% x
and y scale. That makes a bunch (10) of concentric circles at once,
line thickness may also diminish, but that's easy to fix.
Finally, if you want to make a set of concentric circles with different
arbitrary diameters, it might just be easiest to make them without
worrying about keeping them all centred, then select them all and
centre them all by using the horizontal and vertical alignment tools.
This assumes you might fare best if you key in the diameters, rather
than trying to get an exact number with the mouse.
