    First of all, 60 minutes = 1 degree. So that converts your 20 degrees 54 minutes to 20.9 degrees. Secondly, a full revolution is 360 degrees or 2\pi radians. Hence, the conversion from degrees to radians is \frac{2\pi}{360} = \frac{\pi}{180}. So your final answer will be computed as 20.9 \cdot \frac{\pi}{180}.
