Answer:
389.1 units² (nearest tenth)
Step-by-step explanation:
<u>Regular polygon</u>: all side lengths are equal, all interior angles are equal.
<u>Apothem</u>: a line drawn from the center of any polygon to the midpoint of one of the sides
<u>Radius</u>: a line drawn from the center of the polygon to a vertex.
Therefore, we have been given the apothem of this regular dodecagon.
<h3><u>Formulae</u></h3>
where:
- n = number of sides
- l = length of one side
- a = apothem (the line drawn from the center of any polygon to the midpoint of one of the sides)
where:
- l = length of one side
- n = number of sides
<h3><u>Solution</u></h3>
First, calculate the length of one side of the regular dodecagon by substituting a = 11 and n = 12 into the apothem formula:
Now substitute n = 12, the found value of l, and a = 11 into the area formula:
Answer:
a prime number is a number greater than 1 that you can only multiply it by one and itself to get that number( it might sound complicated)
