How to draw a pie graph
Answers
Steps of construction of pie chart for a given data:
Starting with the horizontal radius, draw radii, making central angles corresponding to the values of respective components. Repeat the process for all the components of the given data. These radii divide the whole circle into various sectors.
Answer:
The pie chart is a pictorial representation of data relative to a whole. Each portion in the circle represent an element of the collected data. The pie chart represents the composition of various elements in a whole. The total value of the pie chart is always 100%. Each portion in the circle shows a fraction or percentage of the total
Step-by-step explanation:
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
Pie Chart
● If the values of observation/components are expressed in percentage, then the centre angle corresponding to particular observation/component is given by
Pie Chart
Steps of construction of pie chart for a given data:
● Find the central angle for each component using the formula given on the previous page.
● Draw a circle of any radius.
● Draw a horizontal radius
● Starting with the horizontal radius, draw radii, making central angles corresponding to the values of respective components.
● Repeat the process for all the components of the given data.
● These radii divide the whole circle into various sectors.
● Now, shade the sectors with different colors to denote various components.
● Thus, we obtain the required pie chart.
