A typical record album is 12in in diameter and plays at 33 1/3 revolutions per min. What is the angular speed of a record album?
Can someone show me how to do this?? I'm so lost!!

33 1/3 revolutions per min
= 100/3 rpm
since 1 rotation (revolution) = 360° or 2π radians
the angular velocity = 100/3(360° per minute or 12 000°/min
in radians it would be 100/3(2π) rad/min = 200π/3 rad/min
of course if you wanted it per second, you would divide each of the above by 60
