can't figure out this physics problem...please help!?

A high-speed sander has a disk 4.00 cm in radius that rotates about its axis at a constant rate of 1100 revolutions per minute.
Determine the angular speed of the disk in radians per second.

Determine the linear speed of a point 1.60 cm from the disk's center.

Determine the centripetal acceleration of a point on the rim.

Determine the total distance traveled by a point on the rim in 1.60 s.
