Pie charts are the specific types of data representation, where data is represented in the form of a circle. In a pie chart, a circle is divided into various sectors or segments such that each sector or segments represents a certain proportion or percentage of the total.
In a pie chart, total of all given items are equated to 360° and the degrees of angles, representing different items are calculated proportionately.

Illustration for Pie Chart
From the given pie-chart, we can calculate the following
• Population in any zone when the total population is given.
• Population of any zone as a percentage of that of another zone.
• Percentage increase in the total population given the percentage increase in the population of one or more zones.
