Answer 2

Answer:

Area of Semicircle

The area of a Semicircle is half of the area of the circle .As the area area of a circle is

$\pi \: r ^{2} .so \: the \: area \: of \: semicircle \: \\ is \: \frac{1}{2 \: } (\pi \: r ^{2} ) \: where \: r \: \\ is \: the \: radius \: the \: value \: \\ of \: \pi \: is \: 3.14 \: or \: \frac{22}{7}$
