## Main Question or Discussion Point

When I type "drag coefficient" in Google, and view some of the images, the standard list of geometrical shapes come into view, such as this one:

If we take the cone for example, there is a drag coefficient of 0.50. But I can't see the degrees, or the angle of the sides. Is not that very relevant?

Is there a "standard cone" with certain ratios?
