1) A metal alloy contians the following metals. Represent the data by a pie chart.
SOLUTION 1 : Central angle for a component = ( value of the component / Total value ) x 360° Total value = 80 + 120 + 100 +170 + 80 = 650 = x360 = 48°
|
2) The number of students in a hostel speaking different languages is given below.
SOLUTION 1 : Central angle for a component = ( value of the component / Total value ) x 360° Total value = 36 + 12 + 9 + 6 + 5 + 4 = 72 = x360 = 180°
|
3) A metal alloy contians the following metals. Represent the data by a pie chart.
SOLUTION 1 : Central angle for a component = ( value of the component / Total value ) x 360° Total value = 60 + 100 + 80 +150 + 60 = 450 = x360 = 48°
|
4) Yugendran's progress report card shows his marks as follow.
SOLUTION 1 : Central angle for a component = ( value of the component / Total value ) x 360° Total value = 72 + 60 + 84 + 70 + 74 = 360 = x360 = 72°
|
5) Yugendran's progress report card shows his marks as follow.
SOLUTION 1 : Central angle for a component = ( value of the component / Total value ) x 360° Total value = 72 + 60 + 84 + 70 + 74 = 360 = x360 = 72°
|
6) There are 36 students in class VIII. They are members of different clubs.
SOLUTION 1 : central angle for a component = (value of the component) / (total value) x 360° total value = 22 + 16 + 20 + 18 = 76 central angle = x 360° = 120
|
7) In a school the number of students interested in taking part in various hobbies from class VIII is given below. Draw a pie chart.
SOLUTION 1 : Central angle for a component = ( value of the component / Total value ) x 360° Total value = 20 + 25 + 27 + 28 + 20 = 120 = x360 = 60°
|
8) The number of students in a hostel speaking different languages is given below.
SOLUTION 1 : Central angle for a component = ( value of the component / Total value ) x 360° Total value = 36 + 12 + 9 + 6 + 5 + 4 = 72 = x360 = 180°
|
9) In a school the number of students interested in taking part in various hobbies from class VIII is given below. Draw a pie chart.
SOLUTION 1 : Central angle for a component = ( value of the component / Total value ) x 360° Total value = 20 + 25 + 27 + 28 + 20 = 120 = x360 = 60°
|
10) There are 36 students in class VIII. They are members of different clubs.
SOLUTION 1 : central angle for a component = (value of the component) / (total value) x 360° total value = 12 + 6 + 10 + 8 = 36 central angle = x 360°
