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
