societies likewise also have couple advantages of non-civilized‚ hunter-gatherer societies. One may see the increased likelihood of disease in major‚ populated agricultural societies as a drawback‚ but in reality the exposure to disease and bacteria converts the primitive human immune system‚ into stronger defenses of future identical diseases‚ reducing the likelihood of another identical outbreak. Secondly‚ a major advantage that agricultural societies possess is that they always have the guarantee

the radius so we let a=1. We now have the formula for the area of a polygon with n sides. This formula is Pn=1/2nSn. In this formula Pn represents the area of a polygon with n sides. If you go through the formula you will get pi and eight of its decimal places when there are 98‚304 sides‚ which will give you 3.14159265. (13Ma3) The next proof I will be talking about is Archimedes’. The method Archimedes used for finding pi was to take the perimeters of polygons inscribed and circumscribed about
