A particle with constant speed is moving around the circle from point P to R in 6 sec-onds. The radius of the circle is 100 feet, and the measure of the central angle a is 330°.

a. Find the length of the arc s (to nearest foot).

b. Find the linear velocity v (to nearest foot per second).

c. Find the angular velocity a (to nearest radian per second).
