a.) v = 54Π cm / min, w = 1.5 rev / min

b.) Ø = 315⁰, t = 15 sec

c.) Ø = 3Π/2, r = 35 cm

d.) s = 25.4 cm, r = 19 cm

e.) r = 25 cm, w = 8Π rad / min

Given Formula's:

v = wr

Ø = s/r

r=s/Ø

Very urgent i only need one answer per problem. So if there's someone can answer at least one of it. please help.
