__Concept__:

Relationship between Degree and Radian:

- To convert x radian into degree multiply x by \(\frac{{180}}{\pi }\)
- To convert x degree into radian multiply x by \(\frac{\pi }{{180}}\)

__Calculation__:

**Given:**

Here, we have to convert \(\pi\over 12\)radian.

As we know that, in order to convert x radian into degree we have to multiply x by \(180\over \pi\)

\({\pi\over 12} = ({{{180\over \pi}\times {\pi\over 12} }})^o = 15^o\)
