If the data of Rainfall of City 1 is represented through a Pie chart, then what will be the central angle (nearest to 0.1 degree) corresponding to D1?
Answer & explanation
Correct answer: option 4
⇒ Total rainfall of city 1 = 82 + 78 + 76.2 + 81.6 + 79.4 + 84 + 83.8 = 565
⇒ Central angle corresponding to D1 in city 1 = \(\frac{82 }{565}\) × 360º
= 52.2º
