The Earth travels in a circular orbit around the Sun at 29.79 km/sec. If the radius of
the orbit is 1.496 108 km, what is the angular velocity in radians/sec? (Round to
three significant digits.)

Is that radius 1496108 km ?
so the circumference of the orbit would be
9400323.8 km
at a rate of 29.79 km/sec
it would take 9400323.8/29.79 seconds
or appr. 315553 seconds
angular velocity = 2π/315553 rad/sec
or .00002 radians/sec
