Total distance to be travelled = 4.4 km
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000

heya frnd!
here's ur answer...
given the diameter of the wheel is 70km.
therefore it's radius will be=70/2
=35cm
circumference of the wheel=2πr
=2×22/7×35
=44×5
=220cm
we know that 1km=100000cm
therefore 4.4km=440000cm
no. of revolutions it will take to cover that distance=440000/220
=2000
hence it will take 2000revolution to cover 4.4km
hope this helps..!
