Answer:
hope it helps you
Step-by-step explanation:
Calculate the central angle for each component, given by
Central angle of component = Value of the componentTotal value × 360°
2. Draw a circle of convenient radius.
3. Within this circle, draw a horizontal radius.
4. Starting with the horizontal radius, draw radii making central angles corresponding to the values of the respective components, till all the components are exhausted. These radii divide the whole circle into various sectors.
5. Shade each sector with different design.
This will be the required pie chart for the given data.
Pie chart examples on how to do a pie chart:
1. Mr. Bin's with a yearly salary of $ 10800 plans his budget for a year as given below:
Item Food Education Rent Savings Miscellaneous
Amount (in dollar)
3150
1950
2100
2400
1200
Represent the above data by a pie graph.
Solution:
Total amount earned by Mr. Bin in a year = $ 10800.
Central angle of component = Value of the componentTotal value × 360°
Calculation of central angles
Item Amount (in $) Central Angle
Food
3150
(³¹⁵/₁₀₈₀₀ × 360)° = 105°
Education
1950
(¹⁹⁵/₁₀₈₀₀ × 360)° = 65°
Rent
2100
(²¹/₁₀₈₀₀ × 360)° = 70°
Savings
2400
(²⁴/₁₀₈₀₀ × 360)° = 80°
Miscellaneous
1200
(¹²/₁₀₈₀₀ × 360)° = 40°
Construction of making pie chart
Steps of construction:
1. Draw a circle of any convenient radius.
2. Draw a horizontal radius of this circle.
3. Draw sectors starting from the horizontal radious with central angles of 105 degree, 65 degree, 70 degree, 80 degree and 40 degree respectively.
4. Shade the sectors differently using different colors and label them.
Thus, we obtain the required pie chart, as shown in the given figure.
2. The data on the mode of transport used by 720 students are given below:
Mode of Transport Bus Cycle Train Car Scooter
No. of Students
120
180
240
80
100
Represent the above data by a pie chart.
Solution:
Total number of students = 720.
Central angle for a mode of transport = Number of students using that modeTotal number of students × 360°
Calculation of central angles
Mode of Transport No. of Students Central Angle
Bus
120
(¹²/₇₂₀ × 360)° = 60°
Cycle
180
(¹⁸/₇₂₀ × 360)° = 90°
Train
240
(²⁴/₇₂₀ × 360)° = 120°
Car
80
(⁸/₇₂₀ × 360)° = 40°
Scooter
100
(¹/₇₂₀ × 360)° = 50°
Construction for creating pie chart
Steps of construction:
1. Draw a circle of any convenient radius.
2. Draw a horizontal radius of this circle.
3. Draw sectors starting from the horizontal radious with central angles of 60 degree, 90 degree, 120 degree , 40 degree and 50 degree respectively.
4. Shade the sectors differently using different colors and label them.
