Spar (retailer) throughout Asia, Africa and Oceania. In fiscal year 2017, SPAR achieved €34.5 billion ($40.1 billion) in global sales, which represented a 5.3 percent increase over 2016. The SPAR motto is "under the tree" The name was originally DE SPAR, an acronym of the Dutch phrase (). The acronym was chosen in order to resonate with the verb "sparen", which (related to English "spare") means "save [money]" in Dutch and some other languages, among them German and Scandinavian languages (with variants such as "spara" or "spare"). The acronym ended up meaning "the fir", after which the logo was chosen. As the
Area of a circle good approximation to the circumference. To compute "u" and "U" for large "n", Archimedes derived the following doubling formulae: Starting from a hexagon, Archimedes doubled "n" four times to get a 96-gon, which gave him a good approximation to the circumference of the circle. In modern notation, we can reproduce his computation (and go further) as follows. For a unit circle, an inscribed hexagon has "u" = 6, and a circumscribed hexagon has "U" = 4. Doubling seven times yields The last entry of the table has ⁄ as one of its best rational approximations; i.e., there is no better
