Question

Out of Rs 540, Rahib spent Rs 90 on bread. Calculate the central angle of the amount spent by him on biscuits. ?​

Answer 1

Answer:

We know:

Central angle of a component =sumofcomponentvaluescomponentvalue×360∘

Here, total sales= Rs480

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

 Activity  Number of workers Sector angles Ordinary bread 260 480260×360∘=195∘ Fruit bread 40 48040×360∘=30∘ Cakes and Pastries 100- 480100×360∘=75∘ Biscuits 60 48060×360∘=45∘ Others 20 48020×360∘=15∘

Now, the pie chart 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 195∘. Draw a sector with the central angle 195∘ 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 direction in the 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.
