Rewrite the given angle in radian measure as a multiple of $\pi$. (Do not use a calculator.) $- 110 ^ { \circ }$
A) $- \frac { 7 \pi } { 18 }$
B) $- \pi$
C) $- \frac { 11 \pi } { 36 }$
D) $- \frac { 11 \pi } { 18 }$
E) $- \frac { 5 \pi } { 9 }$

Quizplus · Accepted Answer

To convert degrees to radians, we use the conversion factor $\frac{\pi}{180}$, where $\pi$ radians is $180^{\circ}$. So we have: 
$$-110^{\circ} = -110^\circ\cdot\frac{\pi}{180} = -\frac{11\pi}{18}$$
Therefore, the answer is choice D.
