  • How the radius and arc are smaller in a smaller concentric circle than the larger circle it is inside of. #197

    never thought i would have to teach myself geometry on youtube in high school but here we are :). thank you tho this video was super helpful !!

    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!

      I don't know CAD, but If I used the same rate of change for decreasing the circles, I'd imagine it would look like a cone as it decreased. Your dilemma made me think of a collapsible wooden basket I saw on Etsy. The guy cut the wood in a spiral. czcams.com/video/EQMYBZDaLz8/video.html
