4-29 Problem Solving

A Circle Graph is a helpful way to organize and compare data.  A Circle Graph is sometimes referred to as a Pie Chart because the pieces look like pieces of pie that you might eat.

The entire Circle Graph represents the whole of something.  For example, in the graph below, the whole Circle Graph is ALL (100%) of the people who volunteer in the Community Garden.

Every Circle Graph is divided into parts.  Each individual piece of the pie tells you how many by the size, label, and number of the piece.  Individual pieces may then be compared to the whole pie or graph.  An individual piece may also be compared to other individual pieces in the pie.  The larger the individual part or piece is, the more it represents.
