Reel Fish Line

What is the angular speed of the reel if the line is being reeled in at a constant speed?
In 8.6 s a fisherman winds 2.0 m of fishing line onto a reel whose radius is 3.0 cm (assumed to be constant as an approximation). (rad/s)
2 meter (200 cm) line will rotate the 3 cm radius reel 200/2*pi*3 rotations. One roration 360deg = 2pi radians.
So the angular speed = 200/(6 pi) * 2 pi /8.6 sec
= (400/6) / 8.6 = 7.75 radians/sec
