## Which of the following is a three-dimensional?

A cube, rectangular prism, sphere, cone and cylinder are the basic 3-dimensional shapes we see around us.

## Is a cube infinitely large?

There are no infinitely large cubes. By definition, squares and cubes are finite. Now, you might try to extend the definitions by, for example, taking the limit as L goes to infinity of a square with sides of length L (an L x L square). But that limit doesn’t exist unless you add some extra conditions.

## When a three-dimensional figure is extend infinitely in all directions?

A plane is a flat surface that extends infinitely in all directions. Given any three non-collinear points, there is exactly one plane through them. A plane can be named by a capital letter, often written in script, or by the letters naming three non-collinear points in the plane.

## Which object is one-dimensional and has infinite length?

line
A line is a one-dimensional figure that is made up of an infinite number of individual points placed side by side. In geometry all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions. Below is line AB or, in geometric notation, .

## What is the volume of a 4d sphere?

A 4 dimensional sphere has two ‘volumes’. An interior volume, which is 4 dimensional, and a surface volume which is 3 dimensional. The formula for its interior volume is V = (1/2)(pi^2)(r^4). The formula for its surface volume is 2(pi^2)(r^3).

## How many dimensions does a ball have?

three-dimensional
A sphere (from Greek σφαῖρα—sphaira, “globe, ball”) is a geometrical object that is a three-dimensional analogue to a circle in two-dimensional space. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space.

## Which of the following are zero-dimensional and have infinite length?

A line has infinite length, zero width, and zero height. Any two points on the line name it.

## What is an infinite one-dimensional figure?

A line is a one-dimensional figure that is made up of an infinite number of individual points placed side by side. In geometry all lines are assumed to be straight; if they bend they are called a curve. A line continues infinitely in two directions.

## Is a ray infinite?

A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray.

## Which of the following are one-dimensional and have infinite length quizlet?

Line, Segment, Ray, and Point. Which figures are one-dimensional and have infinite length? Ray and Line.

## Is a segment infinite?

A line segment, as you pointed out, has an infinite number of points. A line also has an infinite number of points.

## Does a solid have infinite length?

(iv) Surface: A surface has length and breadth but no thickness. Therefore, a surface has two dimensions, that is, it is two dimensional. (v) Solid: A solid has length, breadth and thickness. … A straight line may be extended indefinitely in either direction, that is, straight lines are supposed to be of infinite length.

## What geometric object has a finite length?

A line segment is the portion of a line lying strictly between two points. It has a finite length and no width. A ray can be thought of as a half a line. It has a point on one end, and it extends infinitely in the other direction.

## Does a plane have infinite length?

A plane is a two dimensional space with infinite length and width, and no thickness. In Euclidean geometry, a plane is considered to be “flat”. In other geometries, a plane may or may not be flat.

## Which of the following is considered one dimension?

A line is one-dimensional.

## What has infinite volume?

Gabriel’s horn
Gabriel’s horn (also called Torricelli’s trumpet) is a particular geometric figure that has infinite surface area but finite volume.

## Does a segment have infinite length?

A (line) segment is a finite part of a line between two points, called its end points. A segment has a finite length.

## Does a ray extend forever?

A line is a straight path on a plane that extends forever in both directions with no endpoints. A line segment is part of a line that has two endpoints and is finite in length. A ray is a line segment that extends indefinitely in one direction.

## Can volume infinity?

In three dimensions, the shape with the least amount of surface area per volume contained is a sphere. To increase the volume to infinity means also increasing the surface area to infinity. So we can conclude the limit of surface area as volume goes to infinity, is infinity.

## Do fractals have infinite area?

2D fractal curves don’t enclose an infinite area, but 3D fractal surfaces do have an infinite area. For example this: here the height is varied, and any non-zero height, however small, has infinite surface area. 2D fractal curves don’t enclose an infinite area, but 3D fractal surfaces do have an infinite area.

## What is an infinite length?

The length of (countable) infinity is always zero!

## How does Gabriel’s Horn have a finite volume?

on [1,с) around the x-axis (see the figure). … Hence, even though the Horn extends outward along the x-axis to с, the improper integral does converge, and hence there is finite volume “inside” the Horn.
