Find the length of the arc subtended by a central angle of $ heta $ radians in a unit circle
Answer 1
Maria Rodriguez
To find the length of the arc subtended by a central angle $ \theta $ radians in a unit circle, we use the formula:
$ s = r \theta $
Here, the radius $ r $ of a unit circle is 1. So:
$ s = 1 \cdot \theta $
Therefore, the length of the arc is:
$ s = \theta $
Answer 2
Michael Moore
The length of the arc subtended by a central angle $ heta $ radians in a unit circle can be found using the formula:
$ s = r heta $
Given that the radius $ r $ of a unit circle is 1, we have:
$ s = heta $
