How can one prove the formula for the surface of a cone as well as the volume of a cone without using calculus? Most of the online proofs use calculus.(adsbygoogle = window.adsbygoogle || []).push({});

I ask this because these formulas are used in proving the formula for the volume of a solid of revolution and the surface area of a surface of revolution. So in some sense using calculus to deduce the volume/SA of a cone would be circular logic right?

So is it possible to deduce the volume/SA of a cone without using calculus, and yet the reasoning would be considered analytically rigorous?

Thanks!
