How am I doing this Physics wheel (rev to rad) problem wrong?
A wheel has a radius of 5.51 m. How far does a point on the circumference travel if the wheel is rotated through an angle of 25.8 revs?
I've tried a bunch of different ways... What I think is the correct way is to convert rev to rad... 25.8*2pi=rad and then plug in the rad to Theta=rad/r with Theta being the answer. The answer I get is incorrect when I solve like this.
Help is appreciated... this is holding me up on finishing other problems!

r=5.51
circumference,c=2pi*r
c=34.62
distance traveled =c*revelutions
=34.62*25.8
=893.20m
