A motor cycle is moving with the speed of 47.52 km/hr and the radius of the wheel of the motorcycle is 21 cms.
 Calculate the approximate no of revolutions made by the wheel in one minute.
:
Find the circumference in meters
c = {{{(2*pi*21)/100}}}
c = 1.32 meters
:
Find the no. of meters traveled in 1 min
d = {{{(47.52*1000)/60}}}
d = 792 meters in 1 min
:
Find the no. of rev this is
{{{792/1.32}}} = 600 rpm
