Give inequalities for $r$ and $\theta$ which describe the region in the figure in polar coordinates. The arc shown is circular, and the region extends indefinitely in the $y$-direction. The labeled points along the $x$-axis are $x = 1$ and $x = 3$. (Write infinity to indicate a boundary at infinity, and enter t for $\theta$ if necessary.) $\le r \le$ $\le \theta \le$
