the area of a complete circle can be calculated with the next formula
[tex]A=\pi r^2[/tex]the radio is half of the diameter
r=12/2=6
First, we need to calculate the complete area
[tex]A=\pi r^2=3.14\cdot6^2=113.04[/tex]Because we have a semicircle the area is half of the area of the complete circle
[tex]A_{sc}=\frac{113.04}{2}=56.52m^2[/tex]Asn= area semicircle
The correct answer is C
