Sphere Definition
Sphere is defined mathematically as the set of all points in space that are equidistant from a fixed center point. Each point on the surface is unique and spaced from the center by a predetermined amount. In simple words, a three-dimensional geometric shape that is perfectly round and symmetrical is called a Sphere or we can say sphere is a three-dimensional object without any edges or corners.
Shapes of Sphere
A sphere is a perfectly symmetrical and smooth three-dimensional shape. It encompasses all points within its fixed center and radius. Its surface lacks any sharp edges or corners, offering a seamless appearance. A sphere is formed by continuously curving in all directions from a single point, giving it a perfectly symmetrical and round appearance.
Key characteristics of a sphere’s shape include:
- Radius: Radius of the Sphere is the distance from the center of the sphere to any point on its surface is called the radius.
- Surface: The surface of a sphere is continuous, without any flat or sharp regions.
- Volume: The interior of the sphere contains a three-dimensional space. The volume of the Sphere is calculated by the formula 4/3πr3, where r stands for radius.
- Symmetry: A sphere exhibits rotational symmetry, meaning it looks the same from any angle of rotation around its center.
Sphere: Definition, Formulas, Examples, Shapes, Properties
Sphere is a three-dimensional object that is perfectly round and symmetrical in shape. It is a set of points in 3-D space that are all equidistant from a fixed point(center). The distance from the center to any point on the surface of the sphere is the same, and this distance is called the radius. A sphere is defined in 3 axis whereas a sphere is defined only in 2 axis.
In this article, we have explained everything about the Sphere from the Definition of Sphere, Volume, and Surface Area Formula, to Real-life Examples of Spheres. Let’s get a closer look at Sphere in Detail.
