calculate the number of revolutions made by the wheel of a bicycle over a distance of 42 km if the diameter of this wheel is 68.6 cm
***
circumference of wheel=π*diameter=68.6π cm=distance wheel covered by one revolution
total number of revolutions=total distance traveled/distance covered by one revolution
km=1000 m=10^3 m
cm=.01 m=10^-2 m
number of revolutions made by wheel=42*10^3/68.6π*10^-2=42/68.6π*10^5≈19488
