Question

diameter of 1.4m how many rounds will the wheel take in 1.1km

Answer 1

Diameter of wheel = 1.4 m

Radius = 0.7 m

Circumference = 2* pi *r

= 2* 22 * 0.7 / 7

= 44*0.1

= 4.4 m


Total distance to be travelled = 1.1 km = 1100 m

No. Of revolution = Total distance / Circumference of wheel

= 1100 / 4.4

= 11000 / 44

= 1000/4

= 250

No. Of revolution = 250

Answer 2

circumference of wheel=2πr=4.4 m
total distance=1100 m
no. of rounds=1100/4.4=250rounds
