To solve the problems in Bicycle Wheels, you need to know that the circumference (C) of a circle can be calculated using the formulas C = 2 Π or C = Π d, where r is the length of the radius, d is the length of the diameter and Π is approximately 3.14. You will also need to know that one mile = 5,280 feet.
The rim of the bicycle wheel shown below has a radius of 13 inches. What is the circumference of the rim of the wheel to the nearest 10th of an inch?
If the wheel revolves 500 times how many feet will it have travelled (to the nearest 10th of an inch?
If the bike traveled 2 miles how many revolutions did the wheel have?
If the bike makes 400 revolutions a minute, how many feet will this bike travel in 7 minutes?
