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°.
