| The ratio I computed is (Area*4pi)/(Circumference^2), where the circumference of the country is the combined length of its land borders and its coastlines. The ratio measures how large the actual area is compared to how large it could be with the same circumference, so a circle (which would have the largest possible area) would have a ratio of 1. For some landmarks, an equilateral triangle would have a ratio of .605, a square would be .785, and a regular hexagon would be .907. Just for the record, the countries with the lowest ratios were Micronesia (.0002), Palau (.0025), and Canada (.0028). |
