Question

Find the central angle of a pie chart for the section of the pie chart that represents 20% of the pie

Answer 1

Answer:

According to the question, we have to find the angle of the area which represents 20% of the total pie chart. In this figure, the required area or the 20% area is shaded with orange color. So the angle of the 20% region is 2π5. So the area of 20% = 2×227×5 = 1.26°.
