Diameter of wheel = 112 cm
Radius = 56 cm
Circumference = 2*22*56/7
= 44*8
= 352 cm
Total Distance to be covered = 1km 56m
= 1056 m
= 105600 cm
No. Of revolution = Total distance / Circumference of wheel
= 105600/352
= 300
Radius = 56 cm
Circumference = 2*22*56/7
= 44*8
= 352 cm
Total Distance to be covered = 1km 56m
= 1056 m
= 105600 cm
No. Of revolution = Total distance / Circumference of wheel
= 105600/352
= 300

hii!!
here's ur answer... given the diameter of the wheel is 112cm.
therefore radius of the wheel = 112/2
= 56cm
in metres = 56/100
= 0.56m
circumference of the wheel = 2πr
= 2×22/7×0.56
= 24.64/7
= 3.52m
we know that 1km = 1000m
therefore 1km 56m = 1000+56
= 1056m
hence no. of revolutions it will take to cover 1km 56m = 1056/3.52
= 300
it will take 300 revolutions.
hope this helps..!
