Central Angle = (Percentage of the expenditure / 100) × 360°
Expenditure on cold coffee is 6% and cold drink is 2%,
Central Angle for Cold Coffee = (6 / 100) × 360° = 21.6°
Central Angle for Cold Drink = (2 / 100) × 360° = 7.2°
Total Central Angle = 21.6° + 7.2° = 28.8°
The total central angle for cold coffee and cold drink is 28.8°.
