FACTS ABOUT ONE UP CONES REVEALED

The "foundation radius" of a round cone will be the radius of its foundation; usually this is just known as the radius of the cone. The aperture of the ideal round cone is the most angle in between two generatrix traces; When the generatrix will make an angle θ for the axis, the aperture is 2θ. In optics, the angle θ is called the 50 %-angle of
