Question

the diametre of a car wheel is 42cm, how many revolutions will it make to travel 5.28cm

Answer 1

Answer:

is distance =5.28 cm or 5.28 m

if distance=5.28 m

then it will take 4 revolution

Answer 2

Answer:

In one turn, a bicycle covers a distance equal to the circumference of it's wheel.

Circumference of a wheel= 2*pi*radius

So, in 3 turns it will cover a distance equal to say ‘d',

d= 3*circumference of a wheel= 3*2*(22/7)*28

= 528 cms

Hence, it travels 528 cms in 3 turns.
