Find the area of the green shaded region A enclosed by $r = 2 \cos(\theta)$, $r = 2 \sin(\theta)$, and the $x$-axis. Then, find the area of region B between the two circles $r = 2 \cos(\theta)$ and $r = 2 \sin(\theta)$. Area of region A = help (numbers) Area of region B = help (numbers) Hint: What is the total area of regions A and B?
