How do you find the number of data in a pie chart?
To find the total number of pieces of data in a slice of a pie chart, multiply the slice percentage with the total number of data set and then divide by 100. For example, a slice of the pie chart is equal to 60\% and the pie chart contains a total data set of 150.

How do you find the extended angle in a pie chart?
1 Answer
- In any sector, there are 3 parts to be considered:
- The arc length is a fraction of the circumference. The sector area is a fraction of the whole area. The sector angle is a fraction of 360°
- If the sector is 20\% of the pie chart, then each of these parts is 20\% of the whole.
- 20\%×360°
- 20100×360=72°
