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

Mamont248 [21]

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:

$p=12 \cdot x$

and if we substitute x = 9.25 cm, we find

$p=12 \cdot 9.25 cm=111 cm$

$A = \pi r^2$
$C=2 \pi r$
$\pi r^2 = 50.24$
$\pi r^2/ \pi =50.24/ \pi$
$r^2 = 16$
$r=4$
$C = 2 \pi r$

Two different ways to find the difference for 12-3

Aleksandr-060686 [28]

You can either ask "How much is left when you take 3 away from 12?", or you can ask "How far apart are the numbers 12 and 3 on the number line?"

Another way you could think about it is "what number do I have to add to 3 to get to 12?"
