If, say, $r_1=10$ and $D=1$, then it seems one obtains a disk of radius 11, rather than an annulus with inner radius $|1-10|=9$? Ah, maybe we are interpreting $p_1 \in C_1$ differently. I was interpreting it as $p_1$ inside the circle, but I see that may be a mistaken assumption. If it means $p_1$ on the circle, then you are correct. | |
