Yes, it must because a frustum is only a part of a cone.
A frustum of a cone is that part of the surface of a cone between two planes perpendicular to the axis of the cone; if a cone has base radii r1 and r2 and slant height h, then its area, A is given byA = 2*pi*h*(r1+r2)/2cited from Varberg and Purcell's Calculus textbook, 9ed.; p299.
The frustum of a cone looks like a plant pot and its curved surface area is: pi*(r1+r2)*l whereas r1 is the top radius and r2 is the bottom radius with l being its slanted length.
You get a frustum.
It's a frustum! to find the area of this figure you need to take the area of the entire cone and subtract the area of the mini cone. Let me explain.If you keep extending thesideofthe figure into the direction of the smaller circle, it creates a cone, right? so take volume (1/3 area of base * height) of the entire extended cone (whose base is the bigger circle to the vertex). Then take the volume of the top cone(whose base is the small circle to the vertex). Subtract the small one from the big one, and it gives you the area of the frustum.
i have an answer for both a frustum of a pyramid and a frustum of a cone which do you need frustum of a cone just give both of them
There is no frustum of a cone. There is a frustum, which is a cone with the top cut off parallel to the ground.
A large cone has a greater volume than a small frustum while a small cone has a smaller volume than a large frustum
Yes, it must because a frustum is only a part of a cone.
Yes and it is cone that has part of its top cut off parallel to its base and it looks like a plant pot.

A frustum is a truncated cone or pyramid. In other words, a cone with the top cut off, much like an ice cream cone with a flat bottom.
The frustum of a cone looks like a plant pot and its curved surface area is: pi*(r1+r2)*l whereas r1 is the top radius and r2 is the bottom radius with l being its slanted length.
You get a frustum.
It is called a frustum.
