Question

the radius of the wheel of a car is 42cm find the number of rotation made by the whe in order to cover a distance of 6.6km?​

Answer 1

Step-by-step explanation:

Diameter of wheel=42cm

Distance covered=5.28kms=528000cms

Let's consider the wheel's circumference as the distance covered in one revolution. So, circumference equals 2×π×21cms=131.95cms

Number of revolutions for covering 528000cms= 528000/(2×π×21)= 4001.609 ~ 4002 complete revolutions.
