Answer: 68.1
Step-by-step explanation:
The area of a semi-circle is 1/2 the area of a full circle. The area of a full circle is pi*r^2. Therefore, the area of a semi-circle is:
[tex]Area=\pi r^2/2[/tex]
[tex]Area=\pi (3)^2/2=9\pi /2[/tex]
The area of a rectangle is the length multiplied by the width:
[tex]Area=l*w[/tex]
[tex]Area=6*9=54[/tex]
The net area is the sum of the rectangle and the semi-circle:
[tex]Area=(9\pi /2)+(54)=68.1[/tex]
