Lesson 7-5
Circle Graph
• A circle graph is a graph of data that is
presented in a circle, where the entire circle
represents the whole (100%).
• Each wedge represents a part of the whole.
Sketching a Circle Graph
• Estimate percentages as fractions.
• Start with the largest percentages and work
towards the smaller ones.
Example: 10%, 40%, 50%
Start with 50%. 50% = ½
Now look at
40%. 40%
will be almost
all of the top
half.
The remainder
is labeled with
10%.
