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.
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
Learn MoreHalf a sphere is defined as a hemisphere. The term hemisphere is derived from the Greek word "hemi," which means "half" and the Latin word "shaera," meaning "globe."
Full Answer >The volume of a sphere is found by multiplying four-thirds by pi by radius cubed. The Greek mathematician Archimedes first derived this formula. He also found that the surface area of a sphere equals four by pi by radius squared.
Full Answer >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.
Full Answer >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.
