WebIn an algebraic formulation, we say that the area of a circle is πr2 π r 2 and its circumference is 2πr 2 π r. These are consistent with Archimedes' claim: πr2 = (1/2)⋅r⋅(2πr). π r 2 = ( 1 / 2) ⋅ r ⋅ ( 2 π r). But the ancient Greeks did not have algebra, and they did not have the notion of a real number that we do.
