Question

How do you convert $120$ degrees to radian?

Answer 1

Convert $120$ degrees to radian:

Note that, $\text{Angle in radian=angle in degree}\times \frac{\mathrm{\pi }}{180}$.

$120\times \frac{\mathrm{\pi }}{180}=\frac{2}{3}\mathrm{\pi }$.

$120°=\frac{2\mathrm{\pi }}{3}\text{radian}$.

Hence,$120°$is equal to $\frac{2\mathrm{\pi }}{3}$.
