ANSWER:
Number of revolutions made by the wheel in 1 minute =360
∴ Number of revolutions made by the wheel in 1 second =
60
360
=6
In one complete revolution, the wheel turns an angle of 2π radian.
Hence, in 6 complete revolutions, it will turn an angle of 6×2π radian, i.e., 12π radian
Thus, in one second, the wheel turns an angle of 12π radian.
