Possible coordinates on a circle (SAT). Game on.

The center is $(7, 3)$ and the radius is $5\textsf{.}$ A point on the circle must satisfy $7 - 5 \le a \le 7 + 5\textsf{,}$ so $2 \le a \le 12\textsf{.}$ The value $9$ is in this interval.

The center is $(4, -5)$ and the radius is $6\textsf{.}$ A point on the circle must satisfy $4 - 6 \le a \le 4 + 6\textsf{,}$ so $-2 \le a \le 10\textsf{.}$ The value $3$ is in this interval.

The center is $(9, 2)$ and the radius is $8\textsf{.}$ A point on the circle must satisfy $2 - 8 \le b \le 2 + 8\textsf{,}$ so $-6 \le b \le 10\textsf{.}$ The value $4$ is in this interval.

The center is $(-6, 4)$ and the radius is $10\textsf{.}$ A point on the circle must satisfy $-6 - 10 \le a \le -6 + 10\textsf{,}$ so $-16 \le a \le 4\textsf{.}$ The value $-11$ is in this interval.

The center is $(2, 8)$ and the radius is $9\textsf{.}$ A point on the circle must satisfy $2 - 9 \le a \le 2 + 9\textsf{,}$ so $-7 \le a \le 11\textsf{.}$ The value $5$ is in this interval.

The center is $(-1, -10)$ and the radius is $12\textsf{.}$ A point on the circle must satisfy $-1 - 12 \le a \le -1 + 12\textsf{,}$ so $-13 \le a \le 11\textsf{.}$ The value $6$ is in this interval.

The center is $(-8, 6)$ and the radius is $13\textsf{.}$ A point on the circle must satisfy $6 - 13 \le b \le 6 + 13\textsf{,}$ so $-7 \le b \le 19\textsf{.}$ The value $11$ is in this interval.

The center is $(-2, 15)$ and the radius is $14\textsf{.}$ A point on the circle must satisfy $-2 - 14 \le a \le -2 + 14\textsf{,}$ so $-16 \le a \le 12\textsf{.}$ The value $-5$ is in this interval.
