This applet is designed for further understanding of the pie charts discussed in AQR Section 16.
Drag [color=#c51414]point [i]A[/i][/color] or [color=#c51414]point [i]B[/i][/color] to change the percent of the total area of the circular region on the left. Observe how the measure of the central angle of the sector on the right changes. For a few cases, confirm with calculations that the central angle measure is correct for the associated percentage.
