Question

Rihan noticed that each wheel of his bicycle had diameter of 1.75 m. Find the number of complete revolutions
of each wheel, if he has to
bicycle a distance of 22 km​

Answer 1

Answer:

4000 revolutions

Step-by-step explanation:

Diameter = 1.75m

Radius = 1.75/2 m

Circumference / Perimeter of the circle = 2πr

= 2 x 22/7 x 1.75/2

= 5.5m

converting km into m

so, 22km = 22000m

Number of revolutions = 22000/5.5

= 4000
