Question

The radius of a wheel of a car is 35cm.How many revolutions will it make to travel 33km?

Answer 1

Hi friend
---------------
Your answer
--------------------

Radius of a wheel = 35 cm

Distance to be covered = 33 km = 3300000 cm

Now,
----------

Circumference of the circle = 2 × π × r

=> (2 × 22/7 × 35) cm

=> 220 cm

So,
------

Number of revolutions required to cover 33 km or 3300000 cm =

3300000/220 revolutions

= 1500 revolutions

HOPE IT HELPS

Answer 2

Answer:

1500 revolutions.

Step-by-step explanation:

Radius of a wheel = 35 cm

Distance to be covered = 33 km = 3300000 cm

Circumference of the circle = 2πr

= 2 × 22/7 × 35

= 220 cm

No.of revolutions required to cover 33km

= 3300000/220

= 1500 revolutions

Hope it helps my dear friend! Yours lovingly, Jayan.
