Given that,
The diameter of a semicircle is 2 mm.
To find,
The area of the semicircle.
Solution,
Radius of semicircle, r = 1 mm
The area of a semicircle is given by the formula as follow :
[tex]A=\dfrac{\pi r^2}{2}\\\\=\dfrac{3.14\times (1)}{2}\\\\=1.57\ \text{mm}^2[/tex]
So, the area of the semicircle is [tex]1.57\ \text{mm}^2[/tex].
