Question

in how many revolutions can a bicycle wheel of diameter 4.6m cover a distance of 46.2km.​

Answer 1

Step-by-step explanation:

Diameter of the wheel=4.6m

Radius of the wheel=4.6/2=2.3

Circumference=2

$\pi$

r=2×3.14×2.3=14.444m

Number of rotation made by the wheel in going 46.2km or 46200m=46200×14.444

=667312

Hence the required number of rotation=667312
