8. Circle Graph A circle graph, also called a pie chart, shows how a set of data is divided into parts.

9. A circle measures 360 degrees

10. The entire circle contains 100% of the data.

11. Each sector or slice of the circle represents one part of the entire data set.

12. A circle measures 360 and the sector makes up a part of the 100% of the circle. To find the measure of the angle you must set up a proportion.
