Percentage of the different products of a village in a particular district are given below. Draw a pie-chart representing this information.
Central angle of a component = (component value/sum of component values x 360ο)
Here, the total % of items = 100
Thus, the central angle for each component can be calculated as follows:
|Item||In %||Sector angle|
|Wheat||125/3||41.66||41.66/100 x 360 = 149.97|
|Pulses||125/6||20.83||20.83/100 x 360 = 74.98|
|Jwar||25/2||12.5||12.5/100 x 360 = 45|
|Groundnuts||50/3||16.66||16.66/100 x 360 = 59.97|
|Vegetables||25/3||8.33||8.33/100 x 360 = 29.98|
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 149.97o. Draw a sector with the central angle 149.97o 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 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 the figure below.
