(c) The photograph alongside shows a burglar bar made from circular patterns. The diagram below is a representation of a part of the burglar bar in the Cartesian plane. The diagram consists of five circles. Four of the circles have equal radii and intersect each other. The fifth circle drawn touches each of the four other circles at K, L, M and N respectively.
