## THIS USER ASKED 👇

**What is the arc length of an angle of 2π 3 radians formed on the unit circle? a) π 3 b) 2π 3 c) 4π 3 d) 5π 3**

## THIS IS THE BEST ANSWER 👇

We know that

in a unit circle the radius is 1

therefore

[Length of a circumference]= 2 * pi * r> 2 * pi

if 2pi radians have a length> 2 * pi in a unit of circle

2 rad / 3 radians> X.

X = 2pi / 3

the answer is 2pi / 3
