Frequently Asked Questions on Sphere
What is Sphere in 3D Geometry?
A sphere in 3D geometry is a three-dimensional object that consists of all points equidistant from a central point. It is like a 3D version of a circle.
How Many Faces Does a Sphere Have?
A sphere has zero faces, as it is a three-dimensional object with a continuous curved surface.
What is Volume of a Hollow Sphere?
Subtract the inner from the outer sphere to determine the volume of a hollow sphere.
What Is Difference Between a Sphere and a Circle?
Unlike a circle, which exists in two dimensions, a sphere exists in three dimensions.
How to Calculate Total Surface Area of a Sphere?
The Surface Area of a Sphere can be calculated using the formula A = 4πr².
How Many Faces, Edges, and Vertices Does a Sphere Have?
A sphere has zero faces, edges, and vertices, as it is a non-polyhedral, continuous surface.
What are Some Real-Life Examples of Spheres?
Real-life examples of spheres include basketballs, soccer balls, planets like Earth, and objects such as marbles and globes.
How to Calculate Volume of a Sphere?
Calculate the volume of a sphere using the formula (4/3)πr³.
How to Measure Total or Curved Surface Area of a Sphere?
To measure the total or curved surface area (CSA) of a sphere, use the formula: CSA = 4πr2.
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.
