Class 08 Activity – Data handling2

Objective:

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

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

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.

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