Question

I still do not know how to solve this.

Answer 1

I got 346.41 and that isn't one of the answer choices

Answer 2

please help...

Answer 3

area = (½)(apothem)(perimeter)

the apthem is 10 in ur case so just plug in values

here is a helpful website

Answer 4

how can I find the perimeter?

Answer 5

apothem is not 10, according to the link!
Do you know about cosine and sine yet?

Answer 6

no

Answer 7

Okay.. I'll continue thinking! And, according to the website that Nali provided the link to, the perimeter is defined as the added length of each of it's sides.

Answer 8

how do I find the length of each side???

Answer 9

Is this a geometry course you're in?

Answer 10

yes it is

Answer 11

Haha, I don't know off hand, but I'll continue looking! I can tell you what I'm thinking now, if you want. I don't want to mislead, you, though. I just have a plan of action here...

Answer 12

tell me it might help a lot.

Answer 13

Haha, well, it's kinda boggled still.But..
The hexagon is composed of six triangles. The total area you want is six times the area of each triangle (each triangle is a sixth of the hexagon, after all..).
So I want to focus on one triangle's area and multiply it's area by six!
We know the angle of the triangle part that's touching the center. (360 degrees/6)
We know that the triangle is isosceles. (I don't know if I spelled that right).
So the other two angles in the triangle can be determined since a triangle has 180 degrees...

Answer 14

Yay! Each triangle is equilateral! Does that help? :P
