Question 295283
    How many revolution does it take for a 6 inch diameter wheel to travel 15 feet?
.
Circumference = (pi)d = (3.14)6 = 18.84 inches
So, for each revolution of  the wheel, you would have gone 18.84 inches
.
Convert 15 feet to inches:
15 feet * 12 inches/feet = 180 inches
.
180/18.84 = 9.55 revolutions
