Solution to Chart #2

I made this graph using the last website listed in this Topic and a photodraw software program.

To do this by hand you would complete the following chart and then measure the angles using a protractor.  You will not need to actually make a circle graph (using a protractor) on a test but you will need to know the number of degrees in a sector.

 Note: To find the degrees you change the percentage into decimals and then multiply each decimal by 360 to find the number of degrees.
