I have drawn 12 concentric circles on CAD using 144 as the outer radius and subtracting 12's. I want to imagine that I am looking at a cone from the top view. I want to make different cone angles using 12 concentric circles. One angle will be a Phi pyramid angle like the great pyramid of Giza at 51.82729237 Degrees. I want to make other cones using music harmonic ratios, such as 2:1, 3:2, 4:3, etc. How do I calculate the radii or diameters of the circles? I want the cone to match 51.82729237 degrees in 2 dimensions. And different cone angles for music ratios. Thanks for your answers!
