21. First, estimate the size of each piece of the circle graph at the right. Then use your Percent Circle to find the actual percent.
Flavor Estimate Percent
Chocolate Estimates 32% mayStrawberry vary 14%
Vanilla 20%
Cookie Dough 26%
Other 8%
22. Why is it helpful to make an estimate before finding the size of a circle graph?
Answers vary.
