What angle (in racians) between 0 and 2(pi) has the same cosine as \binom{6\pi}{11}

Question

What angle (in racians) between 0 and 2(pi) has the same cosine as
`\binom{6\pi}{11}`

Answer 1

180 degrees is equivalent to pi radians

`\begin{gathered} \text{ }\pi\text{ = 180} \\ \\ \frac{6\text{ }\pi\text{ }}{11}\text{ = p} \end{gathered}`

p = (6 x 180) / 11

`98.18^0`
