Step-by-step explanation:
12. Cos 60° = 8/c
 0,5 = 8/c
 0,5 c = 8
 c = 16
 D² = V16²-8²
 = V256-64
 =V192 = V16×12 = 4V12 
 = 4V4×3 = 8V3
13. Cos 30° = 6/b
 V3/2 = 6/b
 V3 b = 12
 b = 12/V3
 b/Sin B = a /sin A
 b/Sin90° = 6/ sin 60°
 <u>b</u> = <u> </u><u> </u><u> </u><u>6</u><u> </u><u> </u><u> </u>
 1 V3/2
 b× <u>V3</u> = 6
 2
 b = 6× 2/V3
 = 12/V3
 
        
             
        
        
        
After the construction of a circle, we have to "Set the compass to the radius of the circle" so, option C is correct.
<h3>What is a regular hexagon?</h3>
A regular hexagon is defined as a closed shape consisting of six equal sides and six equal angles. The sum of the measure of angles of a regular hexagon is 120 degrees.
Steps to create an inscribed hexagon:
1: The structure needs to adjust the box thickness towards that radius.
2: Afterward moves around the outside of the circular path to just produce the 6 vertices of that similar hexagon.
"Set the compass to the radius of the circle" so, option C is correct.
Thus the above answer is correct.
