Steps:
1. Take the total value of items equal to 360 degrees.
2. Convert all components of the data into degrees using the formula,
Degrees of any component part = (Component value/total value) * 360 degrees.
3. Draw a circle of appropriate radius.
4. Draw any radius preferable horizontal, if the circle, with this radius as base line draw an angle at the centre equal to the degree represented to the first component. This angular ray will tough the circumference of the circle. This sector so obtained with represent the proportion of the first component. Taking the second line as a base draw an angle equal to the degree represented by the second component and so on till all the components are completed.
5. Write the title of the diagram.
Example:
Draw a pie diagram for the given data.
Item of expenditure  Food & Fuel  House & Hygiene  Clothing  Education  Conveyance & Others  Savings 
Amount Spent in Dollars  1500  800  750  600  400  700 
Solution:
Total income of the family = $4,750
Calculation for the diagram
Food & Fuel = $1500 = (1500/4750) * 360 = 114 degrees (Approximately)
House & Hygiene = $800 = (800/4750) */ 360 = 61 degrees (Approximately)
Clothing = $750 = (750/4750) * 360 = 57 degrees (Approximately)
Education = $600 = (600/4750) * 360 = 45 degrees (Approximately)
Conveyance & Others = $400 = (400/4750) * 360 = 30 degrees (Approximately)
Saving = $700 = (700/4750) * 360 = 53 degrees (Approximately)
Directions: Draw the pie diagram for the following data.
1. Draw a pie diagram for the given data.
Item of expenditure  Food & Fuel  House & Hygiene  Clothing  Education  Conveyance & Others  Savings 
Amount Spent in Dollars  1600  1800  950  500  800  800 
2. Draw a pie diagram for the given data.
Item of expenditure  Food & Fuel  House & Hygiene  Clothing  Education  Conveyance & Others  Savings 
Amount Spent in Dollars  1400  1600  1250  1500  1500  1800 
3. Draw a pie diagram for the given data.
Item of expenditure  Food & Fuel  House & Hygiene  Clothing  Education  Conveyance & Others  Savings 
Amount Spent in Dollars  2400  1300  1550  2500  3500  800
