How can you calculate the percentage of a specific category in a pie chart?

• Divide the size of the category's slice by the total size of the pie chart (360 degrees) and then multiply by 100.

• Subtract the size of the category's slice from the total size of the pie chart and then multiply by 100.

• Add the size of the category's slice to the total size of the pie chart and then divide by 100.

• Calculate the percentage based on the color intensity of the category in the pie chart.
