Using the graph below, find values for the radius $r$, the angle $\theta$ (in both degrees and radians), and the coordinates for the point $P$ labeled. (Note: The angle $\theta$ is labeled $Q$ on the graph.)
(a) $r =$

(b) The angle $\theta$ is (give an exact answer) radians

(c) The angle $\theta$ is (round to nearest whole degree) degrees

(d) The point $P$ is help (points).
