Addendum: Come to think of it, the process I described would work
perfectly for vector image content but would lead to loss of resolution
in bitmap editors like the GIMP. Every rotated copy will be an
/approximate/ duplicate of the original model, then an approximation of
the approximation, etc.
So instead, rotate single duplicates of your first layer with the small
image 9, 18, 27 etc. degrees until the circle is filled.
Or try the 1st method, check to see if the results are satisfactory, and
do the slower, one at a time process if not.
