[valeriex0x]

Homework Statement

The once-popular LP (long-play) records were 12 inches in diameter and turned at a constant 33(1/3) rpm.
Find the angular speed of the LP in rad/s and its period in seconds.

Homework Equations

1 rpm=((2∏)/60)

The Attempt at a Solution

for ω i got 3.49

I need help with finding its period in seconds, T.
