  1. 10.5 Problem Solving Skills: Circle Graphs Date ___________________

  2. Circle Graph: • Compares data that are parts of a whole • Uses percents to divide the circle into sectors

  3. Make a circle graph of the following data:

  4. Steps: • Add all of the data to find the total • Find what percent each number is of the total by dividing part by whole and multiplying by 100 • Find the central angles that correspond to each percent by multiplying percent by 360 • Estimate the angles in the circle graph for each type of data

  5. Steps 1 and 2: Total: 9070 + 3023 + 756 + 2267 = 15,116 9070/15,116 = 0.60 60% 3023/15,116 = 0.199 20% 756/15,116 = 0.0500 5% 2267/15,116 = 0.1499 15%

  6. Steps 3: 0.6(360) = 216o 0.2(360) = 72o 0.05(360) = 18o 0.15(360) = 54o

  7. Steps 4: Single-family home Seven or more units buildings Two-family home Three-to-six family home
