Answers
Given : 200 books in a library
Animal stories = 90, Adventure books = 30,
Science books = 40, Travel books = 10 and Fiction books = 30
To Find : Draw a pie chart
Solution:
central angle
Animal stories 90 (90/200) * 360° = 162°
Adventure books 30 (30/200) * 360° = 54°
Science books 40 (40/200) * 360° = 72°
Travel books 10 (10/200) * 360° = 18°
Fiction books 30 (30/200) * 360° = 54°
Total 20 360°
A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion.
In a pie chart, the arc length of each slice (and consequently its central angle and area), is directly proportional to the quantity it represents.
In a pie chart, each sector represents a particular part of data
and the magnitude of the sector is directly proportional to the magnitude of the specific part of the data
Complete pie chart is a circle hence 360° represent complete data
