Hint: First find the angle occupied by each game and then draw the graph.
Here, are the angles occupied by Cricket, Football, Hockey and Basketball respectively.
is the angle, which is used to draw the graph.
Complete step-by-step answer:
To find the we can use this formula.
Here, the given quantity is the number of students playing each game.
Total quantity is the total no of students and is the total angle of a circle.
According to the question:
Total no of students = 40.
No. of students who play Cricket = 20.
No. of students who play Football = 10.
No. of students who play Hockey = 5
No. of students who play Basketball = 5
Now, we need to find the angle subtended by each game on the circle.
angle subtended by cricket =
angle subtended by football =
angle subtended by Hockey =
angle subtended by Basketball =
So now, we have all the data required to draw a circle graph.
the graph will be like
= Cricket
= Football
= Hockey
= Basketball
Note: In the question where the graph is required to draw.
We will 1st process the data. Also we could have made this by finding the percentage covered by each game.
Like the area covered by cricket = Ac.
Ac area.
Similarly
AF = area.
AH = . area
AB = area
Here,
