# RD Sharma Solutions for Class 8 Maths Chapter 25: Data Handling -III (Pictorial Representation of Data as Pie Charts or Circle Graphs)

A pie chart represents the data in a circular format. It is a graph form where the pie slices represent the data's relative size. Thus, it's a form of visual data representation. To create a pie chart, you'll need a list of categories and numerical data. The phrase "pie" refers to the "slices", whereas “entire” refers to the whole portions. The "pie chart," sometimes known as the "circle chart," is a circular statistical visual divided into sectors or slices to demonstrate numerical quantities. Each sector represents a proportional fraction of the overall picture.

The pie chart is a popular method of data display. It comprises several segments and sectors, with each segment and sector of a pie chart accounting for a certain fraction of the total (percentage). The sum of all the sectors representing data equals 360°. Thus, the overall worth of the pie is always one hundred percent. Steps to make a perfect pie chart are as follows:

• Step 1: Enter the data into the table first.
• Step 2: To calculate the total, add all of the values to the table.
• Step 3: To acquire a percentage, divide each number by the total and multiply by 100.
• Step 4: To determine how many degrees are required for each "pie sector," we will draw a whole circle of 360° and do the calculations. The angles would be given by taking out the percentage of 360°. This percentage is the value of the percentage calculated corresponding to the data.
• Step 5: Draw a circle and measure the degree of each sector with a protractor.

The Maths Chapter 25 Data Handling -III (Pictorial Representation of Data as Pie Charts or Circle Graphs) revolves around a unique and easy mode of data representation. The Pie charts are very important to understand, but these graphs are confusing as well. The RD Sharma Solutions provided by the Aakash Institute guides students and helps them understand this important concept.
