Answer:
[tex]A=\dfrac{3.14r^2}{2}[/tex]
Step-by-step explanation:
The area of a circle is given by :
[tex]A=\pi r^2[/tex]
Where
r is the radius of the circle.
If we talk about the area of half of the circle, it means we have to half the area such that,
[tex]A=\dfrac{\pi r^2}{2}\\\\or\\\\A=\dfrac{3.14r^2}{2}[/tex]
Hence, this is the required solution.
