2.Fill in the blank:In a pie chart, each sector represents a particular part of data and the magnitude of the sector isto the magnitude of the specific part of the data.
Answers
Directly proportional
Step-by-step explanation:
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
For example
A 20
B 30
C 40
D 10
Total 100
A:B :C:D = 20:30:40:10
=> A:B :C:D = 2:3:4:1
Angle of sector of A = (20/100) 360 = 72
Angle of sector of B = (30/100) 360 = 108
Angle of sector of C = (40/100) 360 = 144
Angle of sector of D = (10/100) 360 = 36
A:B :C:D = 72 : 108 : 144 : 36
=> A:B :C:D = 2:3:4:1
Same ratio
Hence Directly proportional
