It's fairly easy. Start with the regular tiling of the plane by hexagons. Now inscribe a circle in each hexagon (so you end up with rows of circles, with alternate rows staggered by half width). A little simple mathematics shows that the area of each circle is just over 90% of the area of the circumscribed hexagon.
