Sectors, Areas, and Arcs: Worked Examples (page 2 of 2)

The abbreviation "rpm" for "revolutions per minute" is standard, so you can safely use this notation. The character "ω" is the Greek lower-case letter "omega", and is often the variable used for angular velocity.

Note: This speed isn't as fast as it might appear: it's just under four revolutions per second. You can do that on your bike without breaking a sweat.

This is about eleven miles an hour.
