A wheel makes 180 revolutions in 1 minute. Through how many radians does it turn in 1 second?

Given that Number of revolutions per minute = 180

Then per second, it will be = 180/60 =3

We know that In one complete revolution, the wheel turns at an angle of 2 rad.

Then for 3 complete revolutions, it will take 3 × 2 = 6 radians.
