Explain: How to draw Pie chart?

Steps to draw pie chart :

Pie chart is a circular graph which is used to represent data. In this :

  •  Various observations of the data are represented by the sectors of the circle.
  •  The total angle formed at the centre is 360°.
  •  The whole circle represents the sum of the values of all the components.
  •  The angle at the centre corresponding to the particular observation component is given by,

$\frac{Value of the component}{Total value} \times 360°$

          \frac{Value\ of\ the\ component}{Total\ value} \times 360\degree

Therefore, based on the given data and using the above formula we can construct a pie chart.

Note that the sum of all the angles at the centre should be equal to 360 degrees.
