A circle graph displays data as sections of a circle. The sum of the angle measures in a circle graph is 360°. When the data are given in percents, multiply the decimal form of each percent by 360° to fi nd the angle measure for each section. EXAMPLE 1 Making a Circle Graph The table shows the results of a survey. Display the data in a ...
