To create a circle graph, which step is correct?

• A. Draw an angle for each category based on its percent
• B. Label each segment with the category name
• C. Sort categories from smallest to largest
• D. Find the percent of each, draw an angle that size from the center of the circle

Answer: (D)

In a circle graph, each category’s share is shown as a slice whose size is a central angle that reflects its percent of the total. Since a circle is 360 degrees, the angle for each category should be its percent times 360 degrees. To construct it correctly, you first find the percent for each category, then draw a central angle of that size from the circle’s center to create the wedge. After all wedges are drawn, you label each segment with its category name.

Labeling alone won’t form the slices, and sorting categories by size isn’t part of building the chart. Simply drawing an angle for each category without tying it to its percent (or without converting to the proper angle measure) wouldn’t guarantee accurate proportions. The precise step is converting percent to the corresponding central angle and drawing that angle from the center.
