Question

Define pie chart or pie graph.

Write down the steps for its construction.

Answer 1

A pie chart displays data, information, and statistics in an easy-to-read 'pie-slice' format with varying slice sizes telling you how much of one data element exists.
THE STEPS FOR CONSTRUCTION OF PIE CHART ARE:-

● Find the central angle for each component using the formula given on the previous page.

● Draw a circle of any radius.

● Draw a horizontal radius

● Starting with the horizontal radius, draw radii, making central angles corresponding to the values of respective components.

● Repeat the process for all the components of the given data.

● These radii divide the whole circle into various sectors.

● Now, shade the sectors with different colours to denote various components.

● Thus, we obtain the required pie chart.

Answer 2

$\textbf{Pie Chart }$:

Statistical data can also be represented in the form of pie chart.

Steps for the construction of a pie diagram :

1. Take the total value of all the terms equal to 360°

2. Convert each component of the data into degrees using the following formula.

Degree of any component =( Component value / total value ) x 360°

3. Draw a circle with appropriate radius.

4. Mark the angles at the centre of the circle and draw the sectors.
