Need help with circular motion?

Question

HRW7 4-48E A rotating fan completes 1.61 103 revolutions every minute. Consider a point on the tip of a blade, at a radius of 0.187 m.
(a) Through what distance does the point move in one revolution?
m
(b) What is the speed of the point?
m/s
(c) What is its acceleration?
m/s2
(d) What is the period of the motion?
s

Answer 1

a) C = 2 * pi *R = 2 * pi * .187 = .374pi m
b) S = (.374pi * 1.71) m/s
c)no accleration mentioned, only constant speed mentioned.
d) I Don't understand what you're asking for (motion??)
