If it is desired to transform a square into a circle, a cord is stretched from the centre (of the square) upto its corner (so as to measure out a length equal to half the diagonal). It is (then) stretched (from the centre) towards the (eastern) side. With one-third of the excess part (lying outside the eastern side) added (to the portion of the cord between the centre and the side), the (required) circle is drawn. This is the (approximate) circle, for (almost) as much is added as is cut off (from the corners of the square).
