The pie chart given below shows the expenses of family on different things. The expenses are shown as a percentage of total expenses of the family. What is the difference in central angle made by sector for T1 and T3? Correct Answer 57.6°
Given:
Percentage of T1 = 12%
Percentage of T3 = 28%
Formula Used:
Central angle of sector = (Given % of sector/100) × 360°
Calculation:
Difference between sector T1 and T3 = 28% - 12% = 16%
100% = 360°
⇒ 1% = 360°/100
⇒ 16% = (360°/100) × 16
⇒ 57.6°
∴ The difference between central angle of sector T1 and T3 is 57.6°.
