Question

The measure of an angle in radians is the ratio of the arc length created by the angle to the circle’s radius. If the radius is 6 feet and the arc length is 2π , then define the angle measure in radians.(1 point)

Answer 1

To find the angle measure in radians, we can use the formula:

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

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

Given:
- \( s = 2\pi \) feet,
- \( r = 6 \) feet.

Substituting the values into the formula:

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

Thus, the angle measure in radians is

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

So the correct response is:
