The diameter of a bicycle wheel is 2 feet. About how many revolutions does the wheel make to travel 2 kilometers? Explain. Hint 1 km = 3280ft.

We can work out the circumference of the wheel by using the equation

C = πd

C = π * 2

C = 6.28318530718

C = 6 feet

If 1km is 3280 feet, 2km is 6560 feet

6560 : 6 = 1093.33333333 (recurring)

= 1093

Therefore the bike wheels rolls (approximately) 1093 times to cover 2km.
