What is the volume of a hollow sphere?
As a result, the volume of a hollow sphere equals the sum of the volumes of the outer and inner spheres. The area of the paper that may completely cover the surface of the hollow sphere is known as the curved surface area of the hollow sphere. It is equal to the difference between the CSA of the inner sphere and the CSA of the outer sphere.
What is the difference between a hollow sphere and a shell?
$\begingroup$ Usually, they are referring to the same item. However, it is dependent on the circumstances. It is possible to use the term hollow sphere to refer to both the things I listed above as well as a spherical shell. A hollow sphere can refer to a sphere with a finite thickness as well as a spherical shell, which are both examples of hollow spheres.
What is a sphere in math?
A sphere is a three-dimensional spherical object with a circular form. Spheres have surfaces with points that are equidistant from the center of the sphere. Spheres do not have any edges or vertices, but they do contain volume and surface area, much like other solids.
What is the shape of a spherical object?
Any spherical object is either a round solid or a hollow sphere, with every point on its surface being equally far from its center of gravity. In addition, a spherical item does not have any faces on its surface. Apart from that, there is no flat surface, no edge and no vertex in the case of a sphere, as well.
What is the name of a hollow sphere?

What is the difference between spherical shell and hollow sphere?
The whole charge of a conducting hollow sphere will be concentrated on its outer surface, and the electric field intensity within the conducting hollow sphere will be equal to zero. There will be no field anyplace within a spherical charged Shell since all of the charge will be concentrated on the outside surface of the shell itself.
Is hollow sphere and spherical shell same?
Each of the two shapes has the same radius and charges, which is why they are interchangeable. If both the spherical shell and the sphere are composed of metal, there is no difference since all of the charge will be concentrated on the surface of the sphere in both circumstances. A spherical shell indicates that it is hollow on the inside.
What is the opposite of hollow?
Each of the two shapes has the same radius and charges, which is why they are both called shells. There is no difference between the spherical shell and the sphere if both are constructed of metal, as all of the charge will dwell on the surface of the sphere in either instance. Hollow inside indicates that it has a spherical shell.

How do you know if a sphere is hollow?
If you wish to depict it mathematically, I recommend that you use an inequality as a starting point. A sphere is defined by the fundamental equation, in which is the center of the sphere and is the radius of the sphere. You might describe this as what you’d term a hollow sphere, because only points that are perfectly on the ″shell″ of the sphere would satisfy the equation.
How do you know if a ball is hollow?
Calculate the volume of the ball by measuring it. Weigh it; if it weighs less than the corresponding volume of the material it is composed of, it is hollow, or it contains a core made of a less dense substance than the rest of the object.
