.
Period

Frequency 72 Hz means exactly 72 rotations (or full cycles) per second.
Hence, one rotation (cycle) takes 1%2F72 of a second.
It means that the period is 1%2F72 of a second.

Thus the first question is answered.


Angular velocity.

72 rotations per second means 72%2A2%2Api radians per second, which is 72%2A2%2A3.14 radians per second.
