Question 950419: two wheels are rotating in such a way that the rotation of the smaller wheel causes the larger wheel to rotate. The radius of the smaller wheel is 7.2 cm, and the radius of the larger wheel is 19.5 cm. Through how many degrees will the larger wheel rotate if the smaller one rotates 225 degrees?

The rotation varies inversely as the radius
+7.2+%2F+19.5+=+x+%2F+225++
+7.2x+=+225%2A19.5+
+7.2%2A225+=+19.5x+
+19.5x+=+1620+
+x+=+83.077+
The larger wheel will rotate 83 degrees
