Convert $\dfrac{5\pi}{3}$ radians to degree measure.
A$300^{\circ}$
B$240^{\circ}$
C$270^{\circ}$
D$200^{\circ}$
Answer & Solution
Correct answer: A. $300^{\circ}$
$\theta_{\text{deg}} = \dfrac{180^{\circ}}{\pi} \theta_{\text{rad}} = \dfrac{180}{\pi} \cdot \dfrac{5\pi}{3} = \dfrac{180 \cdot 5}{3} = 300^{\circ}$.
