| No of pupils | 4 | 13 | 30 | 44 | 9 |
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

D
13°
Ask EduPadi AI for a detailed answer
Correct Option: C
Number of pupils = 4 + 13 + 30 + 44 + 9 = 100
Those of 8 - year olds = 13
On the pie chart, the angle represented by the 8-year olds = \(\frac{13}{100} \times 360°\)
= 46.8°
