<p>I remember a section with a problem where a square was inscribed inside a circle. Then the circle had radius r and asked "what is the perimeter of the square in terms of r"</p>
<p>was that one experimental?</p>
<p>Yeah… i don’t remember that question and i had writing experimental</p>
<p>the answer would be 4r RAD(2)</p>
<p>That’s an experimental.</p>
<p>I had that question also, and I’m not certain that it’s experimental but many CC’ers did not have that question, so it’s almost certainly experimental!</p>
<p>Is this the same section where it asks you the distance of x -> s or something like that in PQRS?</p>
