The correct answer is
$\frac{3\pi}{2}$

Converting Degrees to Radians: $270^{\circ}$

To convert an angle from degrees to radians, we use the conversion factor $\frac{\pi \text{ radians}}{180^{\circ}}$.

Calculation Steps

  1. Multiply the angle in degrees by the conversion factor:

    $ 270^{\circ} \times \frac{\pi \text{ radians}}{180^{\circ}} $

  2. Simplify the expression:

    $ \frac{270}{180} \times \pi \text{ radians} $

  3. Reduce the fraction $\frac{270}{180}$. Both numerator and denominator are divisible by 90:

    $ \frac{270 \div 90}{180 \div 90} = \frac{3}{2} $

  4. The result is:

    $ \frac{3}{2} \pi \text{ radians} $

Final Answer

Therefore, the radian measure of $270^{\circ}$ is $\frac{3\pi}{2}$.
