AutoCAD 2013 :: Creating Dartboard With Donuts Only

I have here an exercise to create a Dartboard with just Donuts, limits (0,0)(24,18) GRID=1, SNAP=.125.  Here below what is needed to reproduce.

Now, I have set the center at 30,20, and with the followings:

Layer 1, for the Donut's inner circle with 0 and 0.62 Outer Diameter;

Layer 2, for the next Donut simply 1.50 DIA;

Layer 3, for the Donut 1.50 and 7.50 Outer diameter;

Layer 4, for the Donut 7.50 and 8.25 OD;

Layer 5, for the Donut 8.25 and 13.00 OD;

0, for the outside is just a circle to place the numbers (Not Donut).

Having done to this stage, I got stuck, just going round and round getting nowhere. Here is my attempt (Note that the red radial lines are arrayed around the circle, and done lastly before the numbering):
