Answer:

23.14

Step-by-step explanation:

The semi circular region's diagram looks as if it is half of a circle, cut in half by its diameter.

So the circumference of a circle is 2πr or πd

This is half a circle, so the formula is πd/2

π9/2  =  14.137

However, that's only half of the circumference. That does not contain the diameter that is also included.

So if you add 9m to that you get 23.137
