Pie Charts/Circle Graphs Examples

Example 1

Use a pie chart to show the distribution of animals in a zoo that contains 40 penguins, 20 polar bears, 10 llamas, and 10 jaguars. Well, at least the penguins outnumber the jaguars, so they might have a fighting chance if all of them get loose. #yeahright

Example 2

The pie chart shows the favorite pie flavors of the students in Kelly's class. Use the pie chart to determine if each statement is true or false. Not that it's essential to this exercise, but note the measure of the ratio of the circumference of this chart to its diameter. Also pi. Freaky.

  1. One quarter of the students in Kelly's class like pumpkin pie best.
  2. More than half the students in Kelly's class like blueberry pie best.
  3. Less than one eighth of the students in Kelly's class like pecan pie best.
  4. An equal number of the students like cherry pie best as like lemon meringue best.
  5. Less than one eighth of the students like cherry pie best.
