Detailed explanation-5: -Find the total of all values in the dataset. Divide each segment’s value by the total, to get the corresponding percentage of the total for the pie chart. Multiply this percentage by 360° to calculate the degrees for the pie chart segment. Create a sector with this degree measure in the pie chart.
