    There are 360 degrees in a full circle and there are 2\pi radians in a full circle. The conversion factor from degrees to radians is therefore \frac{2\pi}{360} = \frac{\pi}{180}.

    Here are some examples for you. Convert the following degrees to radians:

    1) 30 degrees = __________ radians.

    30\left(\frac{\pi}{180}\right)=\frac{30 \pi}{180}=\frac{\pi}{6} radians.

    2) 150 degrees = _________ radians.

    150\left(\frac{\pi}{180}\right)=\frac{150 \pi}{180}=\frac{5 \pi}{6} radians.
