If a wheel makes 360 revolution in 1 minutes through how many radius does Turn in one second

Answer»

Here is your answer
NUMBER of REVOLUTIONS made by the wheel in 1 mintue =360
Number of revolutions made by the wheel in 1 second =360/60 = 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.,
12 π radian
Thus, in one second, the wheel turns an angle of 12π radian.
