Question

Shobha spends her day as follows. Represent the data on a pie-chart.

Activity		Time spent (hours)
School		6
Recreation		2
Home work		5
Sleep		7
Other activities		4

Answer 1

Total time spent = 24 hours

Angle at the center of the circle = 360°

Ratio between the angle at the center and total time

= 360°: 24

= 15°

Angle of each sector

Activity		Time spent (in hours)		Angle of the sector
School		6		6 × 15° = 90°
Recreation		2		2 × 15° = 30°
Home work		5		5 × 15° = 75°
Sleep		7		7 × 15° = 105°
Other activities		4		4 × 15° = 60°
Total		24		360°

Following is the required pie chart:
