ًWe should use the compass at one endpoint of line segment.
Adjusting the compass to slightly longer than half the line length
Drawing arcs above and below the segment line.
Keeping the same compass width, draw arcs from other endpoint connecting the arcs cross, and draw the line segment.The inter section between the two lines represents the mid point of the line segment.

Therefore the correct answer is option C
C Use the compass to copy the line segment on two arcs at equal distance from the endpoints if the segment

In order to find the area of the semicircle, or the shaded region, we just have to find the area of the entire circle and divide it by 2. The formula for the area of a circle is $\pi r^{2}$ . With the given diameter of 12, we can deduce that the radius is 6.

Area of Semicircle = ( $\pi 6^{2}$ /2)
Area of Semicircle = (3.14 x 36/2)
Area of Semicircle = (3.14 x 18)
Area of Semicircle = 56.52 $in.^{2}$

Hope this helps!
