**Circle Graphs**A step by step how to.**Example 1**A software company asked 60 owners what they use their computers for most. Of these owners, 21 said word processing, 18 said spreadsheets, 6 said Internet access, and 15 had other responses. Use a circle graph to display these results.**Step 2: Find the percent of computer owners giving each**response. Rememberto find percent set it up as follows… Part x 100 = Percent Whole**Step 3: Use these percents to find the angle measures of the**sectors of the circle graph. To find the angle measure, multiply the percent by 360º. 0.35 x 360º = 126º 0.30 x 360º = 108º 0.10 x 360º = 36º 0.25 x 360º = 90º**Step 5: Use a protractor to draw sectors having**the angle measures found in step 3. 126º .**Step 5: Use a protractor to draw sectors having**the angle measures found in step 3. Word Processing 35% 108º Label each sector with the corresponding response & percent.**Label each sector with the corresponding response & percent.**Step 5: Use a protractor to draw sectors having the angle measures found in step 3. Word Processing 35% 36º 30% Spreadsheets**Step 5: Use a protractor to draw sectors having**the angle measures found in step 3. 90º Word Processing 35% 10% Internet access 30% Spreadsheets Label each sector with the corresponding response & percent.**Step 5: Use a protractor to draw sectors having**the angle measures found in step 3. 25% Word Processing Other 35% 10% Internet access 30% Spreadsheets Label each sector with the corresponding response & percent.**Step 6: Title your circle graph.**Computer Use 25% Word Processing Other 35% 10% Internet access 30% Spreadsheets**Example 2**Recently, in our afternoon tutoring we counted the candy colors in a 1 pound bag of M & M’s. We came up with the following data… red = 109blue = 51green = 23yellow = 95brown = 31orange= 46 purple = 61 Make a circle graph to show the percent of each color of the M & M’s in the 1 pound bag.**Step 1: Organize the data in a table.**46 51 23 109 Yellow 95 31 Brown Purple 61**11 %**46 51 12 % 23 6 % 109 26 % Yellow 95 23 % 31 8 % Brown Purple 61 15%**11 %**40º 46 51 12 % 43º 23 6 % 22º 109 26 % 94º Yellow 95 23 % 83º 31 8 % 29º Brown Purple 61 15 % 54º**After I organized my data in a table, what should I do next?****Complete this circle graph for homework.**& Do circle graph worksheet #2.
