The table above shows the number of pupils in a class with respect to their ages. If a pie chart is constructed to represent the age, the angle corresponding to 8 years old is
A.
48.6°
B.
56.3°
C.
46.8°
D.
13°
Correct Answer: 46.8°
Explanation
Total number of pupils : 4 + 13 + 30 + 44 + 9 = 100
The number of 8 - year olds = 13
The angle represented by the 8-year olds on the pie chart = 13/100 × 360°
= 46.8°
Total number of pupils : 4 + 13 + 30 + 44 + 9 = 100
The number of 8 - year olds = 13
The angle represented by the 8-year olds on the pie chart = 13/100 × 360°
= 46.8°
