How many degrees are \( \frac{19\pi}{12} \) radians?
B. \(285^\circ\)
\( \frac{19\pi}{12}\times \frac{180^\circ}{\pi}=285^\circ\) है। हर (12) हो तो \(15^\circ\) से गुणा करें। / \( \frac{19\pi}{12}\times \frac{180^\circ}{\pi}=285^\circ\). If the denominator is (12) multiply the numerator by \(15^\circ\).
