Answer:

The arc-length of the semicircle is approximately 34.54 units

Step-by-step explanation:

Recall that the arc length of the whole circumference is defined by the formula:

$Circumference's \,\,length=2\,\pi\,R$

where R is the radius of the circle (in your case 11 units)

So the length of half a circumference (which is actually the arc length of the semicircle you are requested to find) would be half of the formula we just mentioned:

$Arc\,\,length=\pi\,R\\Arc\,\,length= 3.14\,(11)\\Arc\,\,length= 34.54\, \,units$

Using x as the variable, write a formula to find the perimeter of the figure. Use the formula to find the perimeter. a regular d

Answer:

c. 12x; 111 cm

Step-by-step explanation:

The regular dodecagon has 12 sides. Each side has a length of x=9.25 cm, and we know that the perimeter of the figure is the sum of the lengths of all the sides: Therefore, since we have 12 sides, the perimeter will be given by the product between the length of each side, x, and the number of sides, 12:

$p=12 \cdot x$
