Question

A bicycle wheel of radius 42cm is rolled over a distance of 66metres.how many revolution does it make?

Answer 1

Hello dear


Here is your answer ~~~~~~~~~~~~~~~~~~~~~~

Given,

radius = 42 cm

Distance = 66 m = 6600 cm

Circumference of the wheel of a cycle = 2πr
= 2×(22/7) × 42 = 264 cm.

Number of revolutions = distance / circumference of wheel

= 6600 cm /264 cm = 25

Hence,

Number of revolutions of cycle = 25 ans.
