Summary

Pie charts

​​In a nutshell

A pie chart shows things as proportions. The size of each sector of the circle tells you how big the proportion is and can be written as a percentage, a fraction or in degrees.

Reading pie charts

​Each shaded part of the circle is a sector. There are 360° in a circle and so each sector has an angle which is a fraction or percentage of 360.​


Example

​The pie chart represents modes of transport taken to school by 20 students. How many students walk?​

Maths; Statistics; KS2 Year 6; Pie charts


The angle at the centre of the walking sector is 90°90\degree90°. Work out this as a fraction of 360°360\degree360°.​

909090 is 14\frac{1}{4}41​​​ of 360360360

​

Work out a quarter of the total number of students: 20.20.20.

​​

14\frac{1}{4}41​​ of 202020 is 555

​​

Five students walk to school.
