## Important Topics for RS Aggarwal Solutions for Class 8 Chapter 24: Pie Charts

**Introduction to Pie Charts**

- The data in a given situation, when represented in the form of a circular graph, with the values, converted into angles using the unitary method, it is known as a pie chart.
- A pie chart is also known as a circle graph.
- The ‘pie’ in the pie chart denotes ‘the whole’ in a given numerical problem whereas the ‘slices’ in the pie given by sectors in the circle represent the data in a quantified way.
- The applications of the pie chart are mainly when we have to evaluate the statistical data in the composition of a whole.

**The Formula of a Pie Chart and Steps to Construct a Pie Chart**

- The angle subtended by the sectors representing the data in a pie chart add up to a total of 360°.
- The data is represented as a fraction of the total data in 360° according to the following formula:

- Once you have evaluated the angles for each given data, you can now construct the sectors data-wise accordingly.

**Uses of Pie Chart**

- Pie charts are very useful in depicting the accounts data such as profit and loss, annual turnover, debts and assets in a business.
- They are also used in representing categorical data.

**Disadvantages of a Pie Chart**

- Pie charts become irrelevant when it comes to depicting large quantities of data.
- It also becomes difficult for the analysis and comparison of data in relatively lesser time using pie charts.
- The interpretation of pie charts becomes complex as the complexity of data increases.
