First put your data into a table and then add up all the values to get the total
Next divide the values by the total and multiply by 100 to get the percent
Now, a full circle has 360 degrees so what we do is multiply the values upon total with 360
Finally; you will get the degrees. Draw a circle and with the help of a protractor draw the degrees
I hope you understand!!!

Draw a circle, then draw a radius. Now, take the percentage of each slot in the pie chat. Calculate like:for example (if percentage is 30) 20/100 * 360 = 72 degrees.
Use a protractor and place on the drawn radius. Measure 72 degrees, mark it and draw a radius to it. Repeat until you do all slots
