To find the angle measure of a circle, you first have to think about how a circle is 360 degrees around. If you're looking for the angle measure of 9 kids out of a total of 15, you'd have to divide 360 by 15 (which is 24) and then multiply that by the number of students you're counting, which is nine students. So, 9 times 24 is 216, which is your central angle
