A cone needs a three dimensional space in which to exist but it's not a solid, it's a two dimensional surface.
Same basic shape, except a cone has three dimensions, a triangle has two.
12' To answer this properly more information is needed about the cone. 12' is just one measure, a cone is a 3 dimensional figure.
A cone has two faces.
A cone does not have any sids. A finite cone has two faces.
A cone has one vertex.

There are way too many variations for that to be possible to answer offhand.
These dimensions are not possible for a right cone. The radius must be less than the slant height. If we reverse the dimensions (radius 6, slant height 9) the total surface area will be about 282.74 units2

There is one face in a cone. It is at the bottom.
a cone has 0 corners
