You can put this solution on YOUR website!
The wheel "unreels" 3 ft of it's circumference
Let +C+ = circumference
+C+=+2%2Api%2Ar+
+C+=+30%2Api+ in
--------------------
+3%2A12+=+36+ in wheel rolls forward
The angle in degrees that the wheel turns is:
+360%2A%28+36+%2F+%28+30%2Api+%29%29+
+432%2Fpi+=+137.51+
137.51 degrees
----------------
