Who knows the Guldin-Pappus theoreme?

  • Thread starter negri

In summary, the Guldin-Pappus theorem is a mathematical theorem that relates the volumes of two solids with the same cross-sectional areas. It was independently discovered by two mathematicians, Paul Guldin and Pappus of Alexandria, in the 17th century. The theorem has many applications in geometry and engineering, particularly in calculating the volume of irregularly shaped objects. It is commonly used in real-life scenarios, such as in engineering and architecture, to calculate the volume of complex objects. The Guldin-Pappus theorem is still relevant and widely used today in various fields of mathematics and engineering.

Hi negri, welcome to PF.

Did you try searching? Because on the first result page Google spits out this which seems quite clear to me.
What do you want us to explain?

ok, now I've looked on to it and there is nothing extra then i already knew, but how can i use it to calculate an equilateral triangle's centroem?
