Question

The diameter of the front wheel of a bicycle is 16
inches while the diameter of the rear wheel is 20
inches. If the front wheel has made 3000 revolutions
to travel a certain distance, how many revolutions
would the rear wheel have made?​

Answer 1

⛄Aɳടɯҽɾ⛄

As we know that:-

↠c = 2π or πd

↠c is the circumference

↠π is 22/7

➯ r is the radius

➯ D is the diameter

↠π × 16 × 3000 = π × 20 × x

• Assumed revolution as x

↠16 × 3000 = 20× x

↠48000 = 20 x

↠ 2400 = x

Answer 2

Answer:

Radius =21cm

Circumference of The Tyre=2πr

= 2x22/7x21

=132 cm

Distance to be covered=924m=92400cm

Therefore number of Revolutions=92400/132

=700

Therefore 700 revolutions
