<p>2 root 2 is what i got but apparently it is wrong</p>
<p>why?? wat is the correct answer</p>
<p>The answer was 4 square root of 2 because you originally got…
Sq. Rt. 32. Divide out 4.
2 Sq. Rt. 8. Divide out 8.
4 Sq. Rt. 2</p>
<p>but it was asking for radius…not diameter</p>
<p>^apparently, most of the other ppl have said it is 2 sqrt 3</p>
<p>look by using a 45 45 90 triangle the diameter would be 4 sq.rt 2…to find the radius, divide by two and consequently the result is 2sq.rt 2</p>
<p>thats how i did it</p>
<p>so IT WAS asking for radius…RIGHT?</p>
<p>…right</p>
<p>can anyone else confirm</p>
<p>You guys are mistaking the diagonal of a square for the diameter of a sphere instead of using the diagonal of the CUBE for the diameter of the sphere.</p>
<p>so wat is the correct answer and how do you find it?</p>
<p>It’s definitely 2sqrt3…the 45-45-90 finds the bottom of the triangle you need to solve for. So, one leg of the triangle is 2sqrt2 and the other leg is 2…the hypotenuse, which si the answer we need, is 2sqrt3.</p>
<p>100% sure about this…I’d explain more, but it’s somewhat of an abstract/visualizing problem.</p>
<p>i understand now…i remember studying that concept about 3 months ago for SATs</p>
<p>Wow, if it’s 2root3, that’s exciting, because I guessed.</p>
<p>Do you know what answer choice 2sqrt3 was? I put C for the last two questions because I ran out of time.</p>
<p>A, you missed it.</p>
<p>yeah, I mistaked the diagonal of the square with the diagonal of the cube too… it was so simple too! </p>
<p><em>facepalm</em></p>
<p>LOLMATH IS LOL…Seriously, this test is easy. It is in no way difficult.</p>
<p>Rational plus rational equals rational</p>
