How to do your measurements on a pie chart having number that are decimals?

To measure a pie chart with decimal numbers, you can follow these steps:

1. Start by determining the total value of the data represented in the pie chart. This will help you calculate the percentage of each data point.

2. Use a protractor or a ruler to measure the angle of the sector corresponding to the data point you are interested in. The angle of the sector represents the percentage of the total value that data point contributes.

3. Calculate the percentage of the total value that the data point represents by dividing the angle of the sector by 360 (the total degrees in a circle) and then multiplying by 100.

4. Once you have the percentage, you can then calculate the actual value of the data point by multiplying the percentage by the total value of the data represented in the pie chart.

5. Repeat this process for each data point with decimal numbers to get accurate measurements for the pie chart.
