Class 08 Activity – Data handling2

Objective: 

To collect data and represent the same as a pie chart.

Materials Required:

 White sheets of paper, colour pencils, geometry box, etc.

Procedure:

Write how much time you spent during the last Monday in the following headings.

2. Now, find the central angle for each activity.

We know that central angle for a component  

= "Value of the component" /"Total value"  x 360°

Central angle for School  = 𝟔/𝟐𝟒 x 360° = 90°

Central angle for Homework = 𝟐/𝟐𝟒x 360° = 30°

Central angle for Play = 𝟐/𝟐𝟒 x 360 ° = 30°

Central angle for Watching T.V. = 𝟑/𝟐𝟒 x 360 ° = 45°

Central angle for sleep  = 𝟖/𝟐𝟒 x 360 ° = 120°

Central angle for others = 𝟑/𝟐𝟒 x 360° = 45°

3. Using a pair of compasses, draw a circle of any convenient radius and divide it into sectors of 90°, 30°, 30°, 45°,120° and 45°

Label the sectors accordingly and shade them using different colours.

Note: 

The data given above is for your comprehension. The students must do the activity and collect the data.
