Answer 1

Answer:

We know:

Central angle of a component =

sum of componentvalues

component value

×360

∘

Here, total expenditure =100%

Thus, central angle for each component can be calculated as follows:

Item Expenditure(in %) Sector angle

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 144∘

. Draw a sector with the

central angle 144∘

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.
