Pi Week Free Video #4:
Finding the Area of Shaded Regions

Let's kick it up a notch. Combination geometry questions combine two or more geometric shapes in the same problem (often including circles), and the harder variations of these questions ask you to find the area of a shaded region. There's no set formula for doing so, so you have to get a little creative. This video breaks it down and shows you exactly how to do that.
