In the formula to solve for the arclength, s, theta should be in _

In the formula for arc length, \( s = r\theta \), where:

- \( s \) is the arc length,
- \( r \) is the radius of the circle,
- \( \theta \) is the central angle,

**\( \theta \) should be in radians**, not degrees. If \( \theta \) is given in degrees, it must first be converted to radians by using the formula:

\[
\theta_{\text{radians}} = \theta_{\text{degrees}} \times \frac{\pi}{180}
\]
