By converting π⁄3 from radians to degrees, answer will be

  • A.55°
  • B.75°
  • C.65°
  • D.60°

Answer: D

\[ \pi \text{ radians} = 180^{\circ} \]

\[ \frac{\pi}{3} = \frac{180^{\circ}}{3} = 60^{\circ} \]

The useful landmarks are \( \tfrac{\pi}{6} = 30^{\circ} \), \( \tfrac{\pi}{4} = 45^{\circ} \), \( \tfrac{\pi}{3} = 60^{\circ} \) and \( \tfrac{\pi}{2} = 90^{\circ} \).
