1: what is the circumference in cm (to the nearest cm)
{{{C = pi*d}}}
------------------
2:what is the circumference in kilometres
1 km = 1000 meters = 100,000 cms
------------------
3:how many times would the wheel turn if the bicycle travels 1 kilometer
Rev = 1000 meters/C in meters = 1000/(pi*0.6366)</PRE>
