प्रश्न

Find the degree measure corresponding to the following radian measure: 
 11c

Advertisements

उत्तर

We have: 
\[\pi \text{ rad }= 180^\circ\]
\[ \therefore 1 \text{ rad }= \left( \frac{180}{\pi} \right)^\circ \]
\[ \left( 11 \right)^c = \left( \frac{180}{\pi} \times 11 \right)^\circ \]
\[ = \left( \frac{180}{22} \times 7 \times 11 \right)^\circ\]
\[ = {630}^\circ \]
