* That a value is ''wrong'' simply because it depends on imprecisely expressed divisors. The ratio that is pi can be derived completely accurately for a whole range of values<ref name="math" /> even if the Sea is taken as a perfect circle, namely when, before rounding to the nearest [[whole number]], the diameter is known to be greater than 9.5 and less than about 9.708, and the circumference greater than about 29.845 and less than 30.5, it being quite common at the time to round to whole numbers.<ref name="jph">{{cite web
