Step-by-step explanation:
- Using fraction to draw the pie chart. Total frequency = 9 + 3 + 6 + 12 = 30. fraction for walk = 9/30. fraction for bike = 3/30. ...
- Using angles to draw the pie chart. Since total angle is 360°, we find central angle for each mode of travel: walk = 9/30 * 360° = 108° bike = 3/30 * 360° = 36°
