Answer B or 2pi/3
Step-by-step explanation:
Its answer B, manged to guess it right.

Using proportions, it is found that the radian measure of the central angle is given by:
[tex]\frac{2\pi}{3}[/tex]
What is a proportion?
A proportion is a fraction of a total amount.
In this problem, we consider that the measure one the entire circumference is of [tex]2\pi[/tex], hence one-third of it is given by:
[tex]C = \frac{1}{3} \times 2\pi = \frac{2\pi}{3}[/tex]
Hence, the radian measure of the central angle is given by:
[tex]\frac{2\pi}{3}[/tex]
