By converting 3π⁄2 from radians to degrees, answer will be

  • A.190°
  • B.150°
  • C.270°
  • D.290°

Answer: C

Use \( \pi \text{ radians} = 180^{\circ} \).

\[ \frac{3\pi}{2} = \frac{3}{2} \times 180^{\circ} = 270^{\circ} \]

That is three quarters of a full turn, which is a useful check: \( 2\pi \) radians is \( 360^{\circ} \), so \( \tfrac{3\pi}{2} \) is three quarters of it.
