Vitruvius, computing miles in the form of the newest constant revolutions of the tires and this flow vehicles, expanded more of several Stadia the outlines of circumferences of your groups of those tires. The guy turned into aware of her or him by pets that gone the newest car. It was first-done of the Archimedes away from Syracuse, which by multiplying the next diameter out-of a group by the half of the circumference put a square quadrilateral equivalent figure to the circle [Footnote 10: Examine No. 1475.].
