You can put this solution on YOUR website!
Express each sport as a fraction
+9%2F21+ of +21+ students play soccer
+1%2F21+ of +21+ students play baseball
etc.
There are +360+ degrees in a circle, so find
what part of a circle each fraction represents
+%289%2F21%29%2A360+=+154.286+ degrees
+%281%2F21%29%2A360+=+17.143+ degrees
+%285%2F21%29%2A360+=+85.714+ degrees
etc.
If you add up all the slices of the pie,
you should get 360 degrees
