Question : The given pie chart represents the survey report on the favourite games of a group of young people.
If a total of 4980 people were surveyed, then what is the central angle produced by the sector indicating football?
Option 1: 108°
Option 2: 105°
Option 3: 100°
Option 4: 90°
Correct Answer: 108°
Solution :
According to the question,
Football = 30%
$\therefore$ Central angle $=\frac{\text{Percentage}}{\text{100}} × 360°=\frac{30}{100}× 360° = 3 × 36° = 108°$
Hence, the correct answer is 108°.
