Question 1 Report
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
Answer Details
To find the angle corresponding to 8 years old in the pie chart, we need to first calculate the total number of pupils in the class.
The total number of pupils = 4 + 13 + 30 + 44 + 9 = 100
Next, we need to find the fraction of pupils that are 8 years old. From the table, we can see that there are 13 pupils that are 8 years old. Therefore, the fraction of pupils that are 8 years old is:
13/100
To find the angle corresponding to this fraction, we can use the formula:
Angle = Fraction x 360°
So, the angle corresponding to 8 years old is:
(13/100) x 360° = 46.8°
Therefore, the answer is option C) 46.8°.
