This applet is designed for further understanding of the pie charts discussed in AQR Section 16.
In the applet below, drag [color=#c51414]point [i]A[/i][/color] or [color=#c51414]point [i]B[/i][/color] 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.
