if r=7 D=14 side of the sq would be 7*2^1/2

campbell_st · Answer

well find the area of the circle... that's important

the diameters of the circles are the diangonals of the square

|dw:1421447677346:dw|

so you can find the side length of the square by using pythagoras' theorem

the reason is the diagonals of a square intersect at right angles

hope it helps
