We know that the area of a circle is [tex]pi * r^2[/tex] so we can take that equation and divide it by two to get your answer. So in this case it would be [tex]\frac{pi*7*2}{2}[/tex]. Hope this helps!
A=pi r^2 radius is 7 bc 14/2 is 7 A= 3.14 7^2 A= 3.14*49 A=153.86 WE ARE NOT DONE 153.86/2 = 76.93 we divide it in half because a semi circle is half of a circle
