2*pi*r=565.484 time taken =565.484/25=22.6194sec so \[\omega\]=2*pi/22.6194=0.2831rad/sec

multiply it with (pi/180) which converts it into radians:)

look at it this way... it's only going 25 m/s ... it's going to take a while to go around the circle once... 2pi/.2777777777 in fact, is how long one complete rev. will take...
