easy

Find the radian measures corresponding to the following degree measures:

$240^{\circ}$

A

$\frac{4}{3} \pi $

B

$\frac{4}{3} \pi $

C

$\frac{4}{3} \pi $

D

$\frac{4}{3} \pi $

Solution

We know that $180^{\circ}=\pi$ radian

$\therefore 240^{\circ}=\frac{\pi}{180} \times 240 \,radian =\frac{4}{3} \pi\, radian$
