1. 1.4 Circle Graphs Circle Graph- a graph that shows how data is divided into categories that do not overlap. Sector- a percentage of the total number of data. (slice)

2. Key- describes the data in each sector. (legend) Solve a simpler problem- Solve a circle graph problem by breaking it into smaller parts.

3. Circle graph- Pie chart Sector- Slice Key- Legend Solve a simpler problem- smaller parts

4. Solve a Circle Graph Problem

5. Estimate the Percentage

8. Part = % Total 100 Total = 80 customers 80 x 10 = 800 ÷ 100 = 8 80 x 40 = 3200 ÷ 100 = 32
