See the FAQ for how to create and plot circles http://matlab.wikia.com/wiki/FAQ#How_do_I_create_a_circle.3F
You can also use fill() or patch() to fill it with color, so you might plot a filled gray one, and then put "hold on" and place a smaller white one on top of it.

Try calling rectangle again with a smaller radius, so you'd have two of them.
