Reading Circle Graphs Worksheets
How to Read Circle Graphs? There is a plethora of different ways you can visually represent data. Dot and plot systems, bar graphs, histograms, line graphs, whisker plots, and pie charts. Pie charts are also sometimes referred to as the circle graphs. To understand what a pie chart looks like, consider a pizza that is cut into pieces. The pieces of this pizza represent the amount of data. Reading a pie chart is as easy as eating a pizza. Each piece of pizza or a pie chart is termed as a sector. just by looking at the size of the sector you can make a lot of evaluations of the data.
Three Pieces of the Pie
To make a circle graph with 3 "pie pieces," evaluate the size of each piece. For instance, say the first piece is 15/30 of the circle, the second piece is 9/30 and the last, 6/30. The numbers are rounded to the 30ths to work them into the 360 circle.
