<p>Brownboi are u sure? That’s what I remember but I don’t want to get happy for nothing.</p>
<p>Oceanz- yeah the radius was 8</p>
<p>should be 2pi<em>(4)</em>(20) = 80pi = 502</p>
<p>Oceanz,</p>
<p>It said the DIAMETER was 8. So the radius is 4. But you could have just multiplied the given DIAMETER by pi to get the circumfrence as well.</p>
<p>pretty sure it went a)96pi…d)96pi+32 e)96pi+64</p>
<p>It asked for the surface area didn’t it? So shouldn’t you have found the Area, not the circumference?</p>
<p>I just skipped the cylinder one, I had no idea how to approach that problem considering it was a hollow cylinder, and was asking for area not volume.</p>
<p>What was the question for the grid in one that equaled 3600</p>
<p>3 wrong 1 omit :s</p>
<p>n=K^2
N divisible by 10 and 24
n is a positive integer</p>
<p>Shaggy, </p>
<p>Lateral surface area (what the question asked for) is height*circumfrence. So you actually have to find both. SO ARE WE SURE THE ANSWER 500 and not 450?</p>
<p>So, can anyone tell which math section was experimental yet?</p>
<p>One of the 20Q 25 min sections was.</p>
<p>Brolex, n was 3600</p>
<p>The cylinder problem required to to think of it as a rectangle, with the diameter as side and the height as another side. Hope this clears up confusion. Answer was 502 -> 500 rounded</p>

<p>I still don’t quite see how the two circles joined together would be a square. There aren’t any pointy edges b/c a circle is supposed to be round. Therefore, how can it be a square?</p>
<p>Alright. I have decided that I will retake this in January. Who’s with me?</p>
<p>i got a math section with a problem that was like 4x+5y+10z=3 what is x+y+z, exp?</p>
<p>borwnboi, that was an experimental.</p>
<p>lol agree with you sunshine, I didn’t see it either. I just took the area of a section which is A=n(degree of sector)/360 *(r^2)(pi), and multiplied by two which was 96pi.</p>
<p>Anyone know if -5 will result in higher than a 700?</p>
<p>The experimental math section was the 25 minute 20 question section that DID NOT have the question about the cylinder’s Lateral Surface Area being 500.</p>
<p>Yes it was exp</p>
<p>You made the square by connecting the radius to the the different points at the intersection of the circles.</p>
