Because it's a nice visual tool, and all the segments will add to a complete whole.
To fill in a pie chart with percents (that all add up to 100%), here's what you do:
(1) Identify the percent of the circle that you want to fill in. Say you want to color 45% of the circle red--that's a pretty big slice. Keep in mind that 45% in decimal form is 0.45 (I just moved the decimal over two places to the left).
(2) Take that decimal, 0.45 in this case, and multipy it by 360, because there are 360 degrees in a complete circle. 0.45*360 = 162, so you will color 162 degrees of the 360 degree circle.
(3) Use a protractor to draw a circle (one half at a time, probably) complete with an origin, the point in the very middle. Also draw one straight line (anywhere) from the origin to the edge of the circle.
(4) Place the 0 degree line on your protractor over the line you just drew. Using the marks on your protractor, mark on the edge of your circle where 162 degrees is, in reference to the first straight line.
(5) Remove your protractor and draw another straight line from the 162 degree mark you made on the edge of your circle to the origin. Between those two lines is 162 degrees, or 45% of a complete circle.
This is process can be repeated for any percentage between 0 and 100.

What is difference between a bar graph circle graph and line graph and when would you use them?
I'm in sixth grade and I use circle graphs in social studies and bar and line graphs in science
What graph measures percents?
pie graphs
What are ways you use percents in every day life?
Taxes, tips, test or quiz grades, graphs.
What is a percent circle?
A circle that can measure percents.
How are linebarand circle graphs similar and how are they different?
Line graphs and circle graphs (or pie charts) both visually represent data, making it easier to identify trends and relationships. They are similar in that they can both display proportions and compare different datasets. However, line graphs are best suited for showing changes over time or continuous data, while circle graphs are ideal for illustrating parts of a whole at a specific point in time. Additionally, line graphs use points connected by lines, whereas circle graphs use sections of a circle to represent proportions.
How are bar graphs and line graphs and circle graphs different?
circle graphs add up to 100% , bar and line graphs don't
Why do you need graphs why are graphs important?
Well we use graphs to show parts compared to the whole. Graphs are important because they can show us percents, they can show us how much of something or whatever you may be talking about. For example, graphs are used to show the percent of people voting for which candidate in this years election.
When we are using circle graph to represent datas?
Circle graphs are use to illustrate the breakdown of a single variable into its components.
What is the sum of the percents in any circle graph?
100
What Tree types of graphs to display data?
line graphs, bar graphs,and circle
What type of graphs are used for qualitative observations?
circle graphs
What is are the differences between circle graphs line graphs and bar graphs?
Circle graphs show data in a circle, while line graphs are akin to join the dots, and a bar graph shows data in vertical or horizontal bars, but all three show the same data results.
