will this help ? suppose a pointP at random is chosen at a distance <1 from O taking P as center and constructing a circle of radius 1, shaded reigon is the common region ,,as P gets closer to O,,space in which any other point can lie becomes lesser.. but how do i prove whole cirlce gets shaded after max 7 points ?

Area of the circle must be \(\pi\). Each point could be imagined as a circle of area \(\pi/4\), maybe?

dw:1344946376091:dw like you see there are maximum 7 points with distance >=1. If I put one more point it's distance with some point will be less than 1
