WebAug 1, 2024 · In mathematics, Pappus's centroid theorem (also known as the Guldinus theorem, Pappus–Guldinus theorem or Pappus's theorem) is either of two related theorems dealing with the surface areas and volumes of surfaces and solids of revolution. WebPappus proved a theorem (which he called "ancient"), which states that the height, hn, of the center of the nth inscribed circle, iCn, above the line segment AC is equal to n times the diameter of iCn. Figure 1. Chain of circles inscribed in the arbelos. Pappus' proof, relying solely on Euclidean geometry, ran over many pages.
