Following data gives the break up of the cost of production of a book:
Draw a pie- diagram depicting the above information.
Central angle of a component = (component value/sum of component values x 360)
Here, total expenditures = 105%
Thus, the central angle for each component can be calculated as follows:
|Printing||30||30/105 x 360 = 102.9|
|Paper||15||15/105 x 360 = 51.4|
|Binding charges||15||15/105 x 360 = 51.4|
|Advertisement||20||20/105 x 360 = 68.6|
|Royalty||10||10/105 x 360 = 34.3|
|Miscellaneous||15||15/105 x 360 = 51.4|
Total : 105%
Now, the pie chat representing the given data can be constructed by following the steps below:
Step 1 : Draw circle of an appropriate radius.
Step 2 : Draw a vertical radius of the circle drawn in step 1.
Step 3 : Choose the largest central angle. Here the largest central angle is 102.9o. Draw a sector with the central angle 102.9o in such a way that one of its radii coincides with the radius drawn in step 2 and another radius is in its counter clockwise direction.
Step 4 : Construct other sectors representing the other items in the clockwise sense in descending order of magnitudes of their central angles.
Step 5 : Shade the sectors with different colours and label them, as shown as in figure below.
