@jaynnn I got C for 16. The height of the isosceles triangles is the slant height, it’s the hypotenuse of a triangle with one leg being the height of the pyramid and the other being the height of the equilateral triangles that make up the hexagon.
(1/3)(Area of hexagon)(height) = 36sqrt(21)
How did people solve #13?
/what did you get for #13?
@student0011 I got B for 13. The quadrilateral is a cyclic quadrilateral so I was able to figure out the values of certain angles and ended up finding out that ABC is an isoceles triangle so AC = BC = 6.
Did aops delete all the 2015 Amc B tests when they updated their website today.
^No…the key is still available.
I got a 114. 
what do you guys thing the cut off would be
I hope it will not be 100.
Is the AMC b cut off always 100? :-?
sometimes its lower, depending on how well other people do
Usually always 100. However AMC 12A last year had a cutoff of 93 and in 2013, 88.5.

When will the official list come out? AIME is coming up really soon :o
Same question as above. And does it matter if I didn’t put my school’s CEEB code on the sheet?
My teacher said it does not matter, as she sent it in with everyone else’s in a big envelope.
Wow the cutoff was 100
