<p>for the square with the circles and you had to find the radius of the small one...i got sqrt 2 -1...anyone else...i though that was right</p>
<p>joe_l514: i got w/4 for that one</p>
<p>joe it was like w=x+y+z what does the arithmetic average or sumthin of w x y and z, i just pluged in numbers for x y and z</p>
<p>it wasn't w/4 because it becomes 2w on the other side...right?</p>
<p>no...its w/2 for sure</p>
<p>hmm.. i got the .704 or w/e but not by guessing.. I made a small 45-45-90 isoc. and just applied properties and the diameter was sqrt 2... so the .704 made sense. can someone explain why that would not have worked...</p>
<p>i'm pretty positive it was w/2.</p>
<p>yea same i got w/4</p>
<p>What did you guys get for the fence problem? Was it 96? (for the grid-in)</p>
<p>//I hate this 60 second limit lol!</p>
<p>a second that griffon</p>
<p>so how bout that little circle radius one still... any takers</p>
<p>carsonne...i got the same answer for that problem as well.</p>
<p>griffon see my post at top of pg 8.</p>
<p>i think its 101 b/c 500/5=100 and then add one for the first post, right?</p>
<p>wait i think i got w/2 or 4 i dunno wait if u plug 1 2 and 3 in for x y and z u get w=6</p>
<p>then u do 6+1+2+3/4 and then wutever is equivelent in the answer, im pretty sure thats how u do it</p>
<p>I concur with griffon. It was w/2</p>
<p>what about the fence problem?</p>
<p>just do the problem again and you'll see its clearly w/2...at one point you had to reduce the fraction 4w/2</p>
<p>the 4 large circles and 1 small circle inside the square</p>
<p>answer: .414 C</p>
<p>yea i got w/2</p>
<p>supersenior i got 101 as well.</p>
<p>edit: fence</p>
<p>shimshimhey: can you explain why?</p>
