Then draw a bar graph showing the expenditure.​

Answer 1

Here, total expenditure = 100 %

So,

The central angle =

× 360°

Hence, the central angle for each activity will be calculated as follows

Steps for construction of representation of data in pie chart

Step 1: Draw the circle of appropriate radius.

Step 2 : Choose a radius anywhere inside the circle.

Step 3 : Now draw a sector of calculated component’s central angle. It is always preferable to choose component with largest central angle first and then continue in descending order of magnitude of their central angle.

Step 4: After drawing sectors, shade them with different colours and label them as shown in the figure.
