4. 2. To show this information in a pie chart, take the following steps: Work out the total number of pupils: 7 + 11 + 6 + 4 + 2 = 30. To work out the angle of each segment, work out the fraction of the total that got each grade.here are 360Â° in a full turn, so to work out the angle, multiply the fraction by 360: 7 / 30 Ã 360 = 84Â°. The grade A sector has an angle of 84Â°. 1  Repeat this process to find the angle of the segments for the other grades.
