Question: What Is A Sphere In Geometry?

sphere, In geometry, the set of all points in three-dimensional space lying the same distance (the radius) from a given point (the centre), or the result of rotating a circle about one of its diameters.

How do you describe a sphere?

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

What is a sphere in simple words?

A sphere is a shape in space that is like the surface of a ball. Usually, the words ball and sphere mean the same thing. The Earth and the Sun are nearly spherical, meaning sphere-shaped. A sphere is the three-dimensional analog of a circle.

What is sphere with example?

A sphere is a three-dimensional object with no vertices and edges. All the points on the surface of the sphere are equidistant from its center. Some real-world examples of a sphere include a football, a basketball, the model of a globe. Since a sphere is a three-dimensional object it has a surface area and volume.

What is the best definition of sphere?

To sphere is defined as to enclose in or put into a round shape. The definition of a sphere is a ball shape where the surface is the same distance from the center at all points or a level of society. An example of a sphere is a globe. An example of a sphere is the upper crust or those in the highest levels of society.

How do you explain a sphere to a child?

A sphere is a perfectly-round3D shapein the shape of a ball. All the points of its surface are equidistant (an equal distance) from its centre, meaning that it is smooth and has noedgesorvertices.

Is an apple a sphere shape?

Apples are relatively spherical except for that characteristic dimple at the top where the stem grows. How do apples grow that distinctive shape?

How many points define a sphere?

A sphere is uniquely determined by four points that are not coplanar. More generally, a sphere is uniquely determined by four conditions such as passing through a point, being tangent to a plane, etc. This property is analogous to the property that three non-collinear points determine a unique circle in a plane.

What are the 4 spheres of the earth?

Everything in Earth’s system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air).

Is a sphere 2d or 3D?
