hiii!!!
here's ur answer...
given the diameter of the wheel is 70cm, therefore it's radius=70/2
=35cm
circumference of the wheel=2πr
=2×22/7×35
=44×5
=220cm
we know that 1km=100000cm
therefore no. of revolution it will take to travel 100000cm=100000/220
=454.54 (approximately)
hence it will take 454 revolution to travel 1km.
hope this helps..!
