hello frnd!
here's ur answer...
given the diameter of the wheel is 70cm.
therefore radius will be=70/2
=35cm
circumference of the wheel=2πr
=2×22/7×35
=44×5
=220cm
in km=220/100000
=0.0022
therefore no. of revolutions to cover 1km=1/0.0022
=454.54(approximately)
hence it will take 455 revolutions.
hope this helps..!

Raunakc:
rose ur answer is also wrong
u got 454.54 revolutions , so that would be 455 approx not 454 approx because of laws of rounding off
yeah sorry
thank you
welcome , i also want to be an ace at this app, just started this app day before yesterday
oh
u will be ace definitely
:)
thanks :)
wlcm frnd!

D = 70cm
R = 70/2
= 35 cm
distance covered in 1 revolution = perimeter
= 2 × 22/7 × 35
= 220 cm
distance needed = 1km = 100000 cm
no. of revolutions = 100000/220
= 454.5454545455
Rounding it off we get 455 revolutions
R = 70/2
