    Radians help

    I need help with this question:

    Suppose an ant walks counter-clockwise on the unit circle from the point (-1,0) to the end point of the radius that forms an angle of 6 radians with the positive horizontal axis. How far has the ant walked?

    what is 6 radians? is it 6 *pi?

    No, a radian is a length of the radius on the circumference.
