Question

lf 20% of expenditure incurred on the construction of a house is on cement ,then the central angle of the sector representing cement in the pie chart would be​

Answer 1

1. Calculate the central angle for each component, given by

Central angle of component = Value of the component/Total value × 360°

2. Draw a circle of convenient radius.

3. Within this circle, draw a horizontal radius.

4. Starting with the horizontal radius, draw radii making central angles corresponding to the values of the respective components, till all the components are exhausted. These radii divide the whole circle into various sectors.

5. Shade each sector with different design.

This will be the required pie chart for the given data.
