How to find Central angle of the part of a pie chart?

Finding the central angle of the part of a pie chart :

The pie chart is a circular graph that 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 center is 360°.

•  The whole circle represents the sum of the values of all the components.

•  The angle at the center corresponding to the particular observation component is given by

              $\frac{Value of the component}{total value} \times 100$
