Question

the radian measure of 120°is?

Answer 1

Given,

The degree measure of an angle = 120°

To Find,

The radian measure of this angle.

Solution,

The formula for converting degree measure to radian measure is

Radian = Degree *π/180

In this case,

Degree = 120

So,

Radian = 120*π/180

Radian = 2π/3

Hence, the radian measure of 120° is 2π/3.

Answer 2

Given: Here we have given angle of 120°

To find: we have to find the radian measure of 120°is?

Solution:

Here for the conversion of degree to radian

we have a formula

$Radian = Degree \times \dfrac {\pi}{180}$

Here we have

Degree = 120

So,

$Radian = 120\times \dfrac {\pi}{180}$

$Radian = \dfrac {2\pi}{3}$

Hence, the radian measure of $120^o$ is$\dfrac {2\pi}{3}$

Final answer:

Hence the answer is $\dfrac {2\pi}{3}$
