how do u determine the section sizes of a circle graph?

Question

please help

Answer 1

i think by known the angle we can apply the laws that state 2sin x known x is the angle

Answer 2

My does the previous answer sound too complicated (not to mention a bunch of B.S.) All you do is find what percent each part of the graph is supposed to represent (take the number in each category divided by the total). You then take each of those percents times 360 degrees (a whole circle) to find how many degrees each angle in your graph should be.
