A cone is a 3D shape that has 1 face, 1 vertices, and 0 edges and 2 examples are a ice cream cone, a traffic cone and a birthday cap
The intersection of the cone and that particular plane is a parabola.
The top of a cone, seen from the outside of the cone, is called the vertex, also referred to as the externalpoint.The vertex is the point of intersection of the lines, or generators, of the cone and the plane base, in this case a circle. But if you just call it the point, everyone will know what you mean.This is referring to what we all think of when we hear the term, cone: a right circular cone. There are other types of cone, but probably not of interest here.
Density or weight is calculated by mass/volume

Cone thread is thread typically used on an overlock "serger" machine. It is thread wound on a cardboard or plastic cone, and is much bigger than a standard thread spool.
Thread size of bolts is calculated by measuring the depth, width, and length of the threads. This helps to identify specific bolts and patterns.
A tea bag thread measures a few centimeters or inches in length.
Put a thread arround the ball and measure the thread's length.
How long is a piece of string? - twice as long as half its length.
Curved surface area of a cone = pi*radius*slant length
Curved surface area of a cone = pi*radiud*length of slant
Sorry, I have no idea where you are, to suggest any place for you. But there are times when I need to hold a large 'cone' of thread at my sewing machine. Put the cone of thread in a large container, and running the thread through the 'eye' of a safety pin ( that you would tape to the sewing machine ) and run the thread past the stem where a spool of thread would normally sit, then thread the machine as usual. It works very well. I hope this is helpful for you.
The curved surface area of a cone is: pi*radius*slant length.
This question cannot be answered. It is the thickness of the thread that matters, not the length.
wrap is the length wise of longitudinal thread in a row while weft is the transverse thread.
