<p>was the number of mondays one experimental?</p>

<p>aleeya- im not sure</p>

<p>How did you solve for the surface area of the cylinder? It said to only find the surface area of the outside of the paper</p>

<p>^ no it was not exp.</p>

<p>No pete, it was 9, I had the right thought process too but put 8.</p>

<p>The one with the median 86 of 101 integers lowest number = 36 right?</p>

<p>Anyone get 500 as answer choice for #7 (math section with grid-ins)? It was asking for the surface area of a right cylinder without a top or bottom. I found the circumference which was 8pi and multiplied that by the height, 20, giving me about 500 for the SA. Anyone confirm?</p>

<p>Yea I got 36. What was the answer to the pollution question? Was it 0.9% or .38%</p>

<p>i also got that mingfs, weird q tho</p>

<p>I put 60 instead of 3600 for the fill-ins </p>

<p>GAHHH</p>

<p>Brolex- yes to the median
MingFs- yes</p>

<p>The lateral S.A. is 2(PI)RH. so it was about 500</p>

<p>VT- </p>

<p>SA = area of top + area of bot + area of side = pi<em>r^2 + pi</em>r^2 + 2pi<em>r</em>h</p>

<p>asked only for side</p>

<p>@bluestring I feel you, I did that too D:</p>

<p>@greenonions17 - :(</p>

<p>i got 450 for the cylinder but i prolly did it wrong</p>

<p>.9 for the c(x) im positive. plug in 80 for c and solve for x</p>

<p>yup, so the cylinder on is just 20<em>circumfrence of a circle with radius 4. So, 20</em>8pi, or 502. Answer was 500.</p>

<p>Anyone know the letter answer for the pollution one?</p>

<p>Can anyone confirm whether 96pi + 64 was choice D or E</p>

<p>@aleeya, e</p>

<p>@brolex, i got .9</p>

<p>^ didn’t the question say that the radius was 8?</p>

<p>Brolex, the answer was A.
Aleeya, the answer was E. </p>

<p>WAIT so is the cylinder’s lateral Surface Area 450 or 500?</p>
