Which of the following is an example of a frustum?

Glass is an example of the frustum of a cone.

What is a frustum of cone give an example of similar shape from your experience?

When we cut a cone by plane into two parts, the part of a cone obtained is called the frustum of a cone. The upper part of the cone remains the same in shape, but the bottom part makes a frustum. A glass tumbler resembles a cone with its pointed part removed. Yes, a tumbler is a resemblance to the frustum of a cone.

How do you find the frustum of a cone?

There are two formulas that are used to calculate the volume of a frustum of a cone. Consider a frustum of radii ‘R’ and ‘r’, and height ‘H’ which is formed by a cone of base radius ‘R’ and height ‘H + h’. Its volume (V) can be calculated by using: V = πh/3 [ (R3 – r3) / r ] (OR)

What is the difference between cone and frustum of cone?

As nouns the difference between cone and frustum is that cone is (label) a surface of revolution formed by rotating a segment of a line around another line that intersects the first line while frustum is a cone or pyramid whose tip has been truncated by a plane parallel to its base.

What do you mean by frustum of cone?

Frustum of cone is the part of cone when it is cut by a plane into two parts. The upper part of cone remains same in shape but the bottom part makes a frustum. To get this part of the right circular cone we have to slice it horizontally or parallel to the base.

How many Frustums can a cone have?

A right circular cone have only one frustum.

How does a frustum shape look like?

A cone is a 3D shape with a base shaped like a circle with the top is pointed upwards. Whereas a frustum is a solid obtained by cutting the top of a cone with a plane that is parallel to the circular base. A frustum of a cone looks like a glass with two circular bases (top and bottom).

What is the shape of frustum?

A frustum is circular if it has circular bases; it is right if the axis is perpendicular to both bases, and oblique otherwise. The height of a frustum is the perpendicular distance between the planes of the two bases.

How do you find the frustum of a pyramid?

If a plane parallel to the base WXYZ of the pyramid cuts it in the plane W’X’Y’Z’ then the portion of pyramid between the planes WXYZ and W’X’Y’Z’ will be a frustum of the given pyramid. The perpendicular distance between this two planes is the height of the frustum.

How many faces does a frustum have?

Frustum

Set of pyramidal frustums
Examples: Pentagonal and square frustum
Faces	n trapezoids, 2 n-gons
Edges	3n
Vertices	2n

How do you make a frustum?

If you cut off the top part of a cone with a plane perpendicular to the height of the cone, you obtain a conical frustum. See figure on the left: the upper base of the frustum has radius r and the lower base has radius R. The height of the frustum is h.

Is a frustum a prism?

In geometry, a frustum (borrowed from the Latin for “morsel”, plural: frusta or frustums) is the portion of a solid (normally a cone or pyramid) that lies between one or two parallel planes cutting it. If all the edges are forced to be identical, a frustum becomes a uniform prism.
