 Items Expenditure(in â‚¹) Central angle Rent 8000 100º Food 10800 135º Clothing 5600 70º Education 3600 45º Savings 800 10º

Construction of pie chart
Steps of construction
1. Draw a circle of any convenient radius.
2. Draw a horizontal radius of this circle.
3. Draw sectors whose central angles are 100º, 135º, 70º, 45º and 10º.
4. Shade the sectors so obtained differently and label each one of them.
Thus, the pie chart is obtained as follows.
