Answer 1

The measure of an angle in radians is given by the formula:

\[
\theta = \frac{s}{r}
\]

where \( \theta \) is the angle in radians, \( s \) is the arc length, and \( r \) is the radius of the circle.

In this case, the radius \( r \) is 6 feet and the arc length \( s \) is \( 2\pi \) feet.

Substituting these values into the formula:

\[
\theta = \frac{2\pi}{6} = \frac{\pi}{3}
\]

Therefore, the angle measure in radians is:

\[
\frac{\pi}{3}
\]

So the correct response is:

**Start Fraction pi over 3 End Fraction**.
