Now that you know how to find a percent of a number, you can make circle graphs! First set up a table that looks like the one shown on the right.
To find the percent of her homework was spent in each subject, you will need to know the total number of minutes that Devynn spent on her homework. Find the total number of minutes that Devynn spent on homework by adding the numbers in that column. How many minutes did Devynn spend to complete all of her homework?
We will fill in the percents column by dividing each subject by the total and then turning the decimal into a percent. (rounded to the nearest whole percent). What percent of the homework was spent on Math?
What percent of the homework was spent on Spelling?
We know the percentages that we want to put in the circle, but we need to know how large of an angle each subject should get. A full circle is 360o. Math should be 28% of 360o. What should be the measure of the angle that will show math on the circle graph?
We will round 100.8 to 100 so that it will be easier to draw. Use the same rounding concept as you determine the measure of the angle that will show Spelling time. What angle should be drawn to show the percent of time spent on Spelling?
Finish filling in your table.
Now use a compass to draw a circle and a protractor to measure out the angles that you have chosen. Choose good colors and you will quickly make an excellent looking circle graph!
