The degree measure of 1 radian is :
[A]57\textdegree32'16''
[B]57\textdegree61'22''
[C]57\textdegree16'22''
[D]57\textdegree22'16''

\mathbf{57\textdegree16'22''}
\therefore 1 radian  = \frac{180\textdegree}{\pi}
= \frac{180\times7\textdegree}{22}
= \frac{630}{11} = 57\frac{3}{11}\textdegree
= 57\textdegree\frac{3}{11}\times 60' = 57\textdegree\frac{180'}{11}
= 57\textdegree16'\frac{4}{11}\times 60'' = 57\textdegree16'22''
Hence option [C] is the right answer.
