Question

The propeller blades on a submarine have a radius of 6 feet. At full speed, they turn at 120 revolutions per minute. What is the angular velocity, in radians per minute, at the tip of the blade?

Answer 1

One revolution also corresponds to an angular displacement of 2π rad.

So, the angular velocity is

120 rev/min = (120 rev/min) * (2π rad/rev) = 240π rad/min

Answer 2

753.98 rad/min

Explanation:

on edge, it asks for you to round to the nearest hundredth, causing me to assume that you need to multiply 240(pi)

the whole answer is 753.9822369, but it asks for you to round.
