Short Answer

Provide an appropriate response.
-A radial line is drawn from the origin to the spiral of Archimedes $r = a \theta , 0 \leq \theta$ , a $> 0$ . Find the area swept out during the second revolution of the radial line that was not swept out during the during the first revolution. In other words, find the area between the first and second turns of the spiral.
