Answer pls I can answer ur question maybe

Answer 1

39.25

Explanation:

5^2=25

25x3.14=78.5

78.5/2=39.25

Answer 2

`C=5\pi \approx15.71`

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:

`C=2\pi r`

Therefore, the circumference of a semicircle is half of that (ignoring the diameter):

`C=\pi r`

The radius is 5.

`C=\pi (5)=5\pi \approx15.71`

The arc length is around 15.71 units.
