<p>dang, I didn’t have a lot of these question
okay, now i’m scared! and i’m not an int’l!
and math was my experimental too!</p>
<p>Hey, so how about that question with the overlapping semicircles with radius r and total length of x? and it asked for the overlapping distance in terms of x and r?</p>
<p>I think that was an experimental (thank god) since I asked my friends who had the same test and nobody seemed to recognize it.
I missed the question.</p>
<p>The answer was 4r-x</p>
