Answer:
[tex]C=5\pi \approx15.71[/tex]
Step-by-step explanation:
The arc length of the semicircle is basically the circumference of it. Therefore, we can use the circumference formula.
The circumference of a full circle is:
[tex]C=2\pi r[/tex]
Therefore, the circumference of a semicircle is half of that (ignoring the diameter):
[tex]C=\pi r[/tex]
The radius is 5.
[tex]C=\pi (5)=5\pi \approx15.71[/tex]
The arc length is around 15.71 units.
