Question

The number of students in a hostel, speaking different languages is given below. Display the data in a pie chart.

Answer 1

For making a pie chart, we need to find the central angle for the number of students speaking different languages.
Central angle for the number of students speaking Hindi = ($\frac{40}{72}$) × 360° = 200°.
Central angle for the number of students speaking English = ($\frac{12}{72}$) × 360° = 60°.
Central angle for the number of students speaking Hindi = ($\frac{9}{72}$) × 360° = 45°.
Central angle for the number of students speaking Hindi = ($\frac{7}{72}$) × 360° = 35°.
Central angle for the number of students speaking Hindi = ($\frac{4}{72}$) × 360° = 20°.
So, the table will be filled as:

Language	Hindi	English	Marathi	Tamil	Bengali	Total
Number of students	40	12	9	7	4	72
Central angle	200°	60°	45°	35°	20°	360°

Now, let’s draw the pie chart for the above data.
We will start with drawing a circle of any radius.
Then, we will draw different sectors based on the central angle.
