Q:

What shape is a sphere?

A:

Quick Answer

A sphere is a round-shaped object in three-dimensional space. All points on a sphere's surface are the same distance from its center point. Some examples of a sphere are a globe, marble, soccer ball and basketball.

Full Answer

In geometry, two important formulas relating to a sphere are how to find its volume and its surface area. Theses formulas are: volume = (4/3) × pi x r^3 and surfaces area = 4 x pi x r^2, where "r" refers to the radius and "pi" is approximated as 3.14.

A sphere is a geometrical object that is also perfectly symmetrical about its center. The distance from a sphere’s center to its surface is called the radius. A sphere does not have any vertices

  • Q:

    How many edges does a sphere have?

    A:

    A sphere lacks edges. Edges are associated with faces and are found in shapes like squares and rectangles. Because of the round shape of a sphere, it lacks faces.

  • Q:

    How many vertices does a sphere have?

    A:

    A vertex is a corner on a polygon, polytope or polyhedron, and when faces, facets or edges of an object come together, a vertex forms; however, because a sphere features no meeting points, it has no vertices. Even though a sphere does have one continuous surface, its lack of meeting points with any other surface means that it technically has no faces. Spheres have no lines, so they also have no edges.

  • Q:

    How do you find the volume of a sphere?

    A:

    Find the volume of a sphere by solving for the equation V=4/3*pi*r^3, where V is volume, r stands for radius and pi is 3.1459. Cube the radius, and multiply that number by pi and 4/3 for the volume. Pi delineates the relationship between a circle's diameter and circumference.

  • Q:

    How many faces, edges and vertices does a sphere have?

    A:

    A sphere has no faces, edges or vertices. By definition, it is a curved three-dimensional geometric figure whose surface is defined as the set of all the points equidistant from its center point.
