Question

a wheel make 450 Revolution per hour the number of radians through which it turns in one second is​

Answer 1

Number of revolutions made by the wheel in 1 minute = 360

∴Number of revolutions made by the wheel in 1 minute =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.

this is how to solve it : just substitute all the terms in your question to all the terms in my answer.
