Question

a wheel makes 360 revolution in 12 minute. through how many radians does it run in one second
​

Answer 1

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.
