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: Option C
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 = (frac{13}{100} times 360°)
= 46.8°
