<p>Hey, I just finished the International Test from about 4 hours; did anyone felt the math section to be very easy .. i mean really really easy ?</p>
<p>For me it was not that easy …especially the cube blocks.</p>
<p>Question number 20, about the length of the side of the square in terms of the radius of the circle. I omitted it. Same for question number 18, that gave the length for a side for 18 cm, and two other sides I can’t remember, and asked you to get the length of a greater side in between.</p>

The answer of the first question is :
r ( the square root of Pi )</p>
<p>The 4th option I believe</p>
<p>@kdines
The the cubes q was confusing , I got it 70 . And I believe that’s correct.</p>
<p>btw there was 1 section in math that was not easy</p>
<p>Lol, please explain it to me man. I spent 5 minutes on that question.</p>
<p>Oh **** , when you told me to explain it I thought about it again and I may have got it wrong . Oh **** i always rush :(<br>
Now I realized the answer is :
r ( square root of 2pi )</p>
<p>FreedomEagle, SirWanksalot Answer to that one was r(square root 2pi), if I remember correctly.</p>
<p>What did you guys get for the one with the multiple rectangles with total area of 64? I think it asked for the perimeter.</p>
<p>Also, what about the one with the two triangles and the unspecified angle x. It asked for the total length of the bottom side?</p>
<p>The area of the circle is (( pi r^2 ))
And the area of the shaded region is the same as the area of the circle so it is (( pi r^2 )) .
So the totall area of the square is : (( 2 pi r^2 ))
Which means that the side of the square is the square root of (( 2 pi r^2 )) = r ( square root of 2 pi )</p>

For the second question I think they asked for x which is 55 .</p>
<p>I was sure Iam getting an 800 in Math 
**** that .</p>
<p>O_O I remember the problem specifically asked for the length of the side. I remember solving for x first, then re-reading the problem to find out that they were not asking for x! Agh someone confirm this!</p>
<p>Also what about the question with the 7 rectangles? With area 64? What was the perimeter?</p>
<p>^^ I omitted that cuz I ran out of time , this was the only section I ran out of time in it .
I think , and hope , that this is the experimental section. Cuz I got 4 math sections .</p>
<p>What did you guys answer for the grid in question that asked for k . The curve in which a point in it was ( 2 , K ) ??</p>
<p>No it’s not, I got that section too and had my experimental in CR 
This particular math section was really hard, and while doing it I was sure it was the experimental, but I was disappointed to discover 4 CR sections in my booklet.</p>
<p>Do you mean the question where you were given a curve and it said to find x where f(x)>k?
I think that was 0.</p>
<p>Oh god . Man you’re killing me :(</p>
<p>It can’t be zero , it should be 3 < k < 7 , i’m sure about that , but i don’t know the answer.</p>
<p>it is zero.I’m sure about that.</p>
