Question 564126: use of this rato: you make a wagon wheel that has a diameter of 3 feet. how many turns of the wheel will it take to have you go the distance of one mile (5280)? if your wheel makes one rotation every second, then what is the velocity in miles per hour for your wagon?

You can put this solution on YOUR website!
Circumference = +C+ ft
Diameter = +d+ ft
+C+=+pi%2Ad+
+C+=+pi%2A3+
In 1 turn of the wheel, it rolls a
length of +C+=+pi%2A3+ ft
1 mile = +5280+ ft
In 1 mile, the wheel makes +5280+%2F+%28pi%2A3%29+=+560.331+ revolutions
+1+ revs/sec x +pi%2A3+ ft/rev x +1%2F5280+ miles / ft x +3600%2F1+ sec/hr = mi/hr
+1%2Api%2A3+%2A%281%2F5280%29%2A3600+=+6.425+ mi/hr
Hope I got it right
