Question

the diameter of a wheel is 1.05m.How many rotation will it make to cover a distance of 3.3km?

Answer 1

Hello...!!!

Diameter = 1.05 m
Radius = 1.05/2 m
= 0.525 m

Circumference = 2 x pi x r
= 2 x 22/7 x 0.525
= 3.3 m
= 0.0033 km

Rotation in 3.3 km
= 3.3/0.0033
= 1000

Hope it helps...!!,
