- 4.0°

Correct Answer Explanation
A circle in a pie chart is thought of having 100 equal parts of 3.6° (360°/100) each.
Key Points:
- Total angle in a circle = 360°.
- Each percentage = 360°/100 = 3.6°.
- To find the angle for each component, multiply percentage by 3.6°.
- Example: If a component is 29.8%, its angle = 29.8 × 3.6° = 107°.
- This is an important formula frequently asked in competitive exams.
Why Other Options Are Wrong
- A. 1.8°: This would imply 200 parts, not 100.
- C. 2.4°: This would imply 150 parts, which is incorrect.
- D. 4.0°: This would imply 90 parts, which is wrong.
