Given diameter of wheel = 126 cm
radius of wheel =
2
126
=63cm
then circumference of wheel =2πr
=63×2×π
circumference =126πcm
∴ In one reduction wheel cover 126πm distance
then
Distance cover is 50 rounds =50×120π
Distance =7300π
Total Distance covered =22.922cm
Total Distance covered by wheel =229.2m
