Step 1:
I'll solve this step by step using precise LaTeX formatting:

Step 2:
: Identify the radius

- From the image, the radius is $$r = 4$$ units

Step 3:
: Recall the formula for the area of a full circle

- The full circle area formula is $$A = \pi r^{2}

Step 4:
: Calculate the area of a semicircle

- So the area will be $$\frac{1}{2} \pi r^{2}
- A semicircle is half of a full circle

Step 5:
: Substitute the radius value

- $$A = 8\pi$$ square units
- A = \frac{1}{2} \pi (16)

Step 6:
: Calculate decimal approximation

- Using $$\pi \approx 3.14
- A = 8 \times 3.14 = 25.12 square units

Final Answer

8\pi or 25.12 square units
