SOLUTION: a square is inscribed in a circle. A side of the circle is 2 radical 2. find circumference of the circle. Leave anser in terms of pi.

You can put this solution on YOUR website!
a couple of assumptions by me to answer your question:

1. i assume you mean "2 radical 2" is
2. i assume this is the length of a side of the square and not circle.

Cut the square in half from one corner to the opposite corner, creating 2 right angled triangles. Use Pythagoras, to find the hypotenuse, a:


so .
Hence a=4

a is the diameter of the circle, so, as the circumference = pi*a. the answer is 4pi.
