AQR Section 16: Circular Sector Investigation (Part 1)
This applet is designed for further understanding of the pie charts discussed in AQR Section 16.
In the applet below, drag point A or point B to change the measure of the central angle of the sector on the left. Observe how the percent of the total area of the circular region changes on the right. For a few cases, confirm with calculations that the percent shown is correct for the associated angle.
