The favourite flavours of ice-creams for students of a school is given in percentages as follows.

Flavours |
Percentage of students Preferring the flavours |

Chocolate | 50 % |

Vanilla | 25 % |

Other flavours | 25 % |

Let us represent this data in a pie chart.

The total angle at the centre of a circle is 360°. The central angle of the sectors will be a fraction of 360°. We make a table to find the central angle of the sectors .

Flavours |
students in preferring the flavours |
In fractions |
Fraction of 360° |

Chocolate | 50 % | `50/100 = 1/2` | `1/2` of 360° = 180° |

Vanilla | 25 % | `25/100 = 1/4` | `1/4` of 360° = 90° |

Other flavours | 25 % | `25/100 = 1/4` | `1/4` of 360° =90° |

1. Draw a circle with any convenient radius. Mark its centre (O) and a radius (OA). (fig.)

2. The angle of the sector for chocolate is 180°. Use the protractor to draw ∠AOB = 180°. (fig.)

3. Continue marking the remaining sectors.
