Calculate the angular velocity of the Earth in its orbit around the Sun and about its axis.

The Earth orbits about the Sun in 365.25 days (roughly), so the answer is 2*Pi divided by 365.25 / 24 / 60 / 60 in radians per second.
Likewise, the Earth revolves around its axis in 24 hours, so the sum is similar. Actually, it revolves around its axis in something less than 24 hours ~ close to 4 minutes short of 24 hours ~ because we measure time from mid-day to mid-day and the position of the earth relative to the sun changes daily.

Simple
180 degrees = 2*pi = angular distance traveled by earth in 1 year
velocity = distance / time
angular velocity = angle / time = 2 *pi / 1 year
Answer: 2 PI/year

Here's a hint: Angular velocity is measured in radians/sec. and a complete circle is 2Ï radians of angular displacement.
