Find the area of the semicircle.

Given:
Given that the radius of the semicircle is 4 units.
We need to determine the area of the semicircle.
Area of the semicircle:
The area of the semicircle can be determined using the formula,
[tex]A=\frac{\pi r^2}{2}[/tex]
Substituting π = 3.14 and r = 4, we get;
[tex]A=\frac{3.14 \times (4)^2}{2}[/tex]
Simplifying, we get;
[tex]A=\frac{3.14 \times 16}{2}[/tex]
Multiplying, we get;
[tex]A=\frac{50.24}{2}[/tex]
Dividing, we get;
[tex]A=25.12[/tex]
Thus, the area of the semicircle is 25.12 square units.
