Given the radius, how do you find the apothem of a regular hexagon?

omg lolz wtf is an apothem and why do i feel i should know that.

The apothem is sqrt(3) * s / 2 where s is one side of one of the six congruent triangles forming the hexagon.

The apothem is the distance between the center and a side. The radius is the distance between the center and a corner.

The distance between the center and a corner would be the length of one of the sides of the triangles, correct?

So sqrt(3) * r / 2 would be the same as sqrt(3) * s / 2.

Here's another two. Please solve (or atleast give me base/height for the second.)

Oh, crap. I posted the wrong circle image...but I figured out the answer.

Still need help on the parallelogram one.

10/11 = x/13

so, uh, 130/11, or like 11.something

11.8 when rounded.

Edit: That answer is so fucking wrong, Latrinsorm.

Second edit: Maybe not, I guessed around 12 ft when I looked at it. Just seems too easy.

STFU no it isn't. The angles are the same, the sines are the same.
