Question

The radius of the wheel of a cycle is 52.5 cm. How many revolutions will it make in
covering 6.6 km.​

Answer 1

here is your answer

Step-by-step explanation:

Let the number of revolution be n

A/q

n× 2πr = distance

distance = 52.8×1000×100 cm

⇒n ×2π 84 = 52.8×1000×100

⇒n = ( 52.8×1000×100 )/(2π×84)

=10000

∴ number of revolution is 10000
