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.
A sphere is a solid geometric figure defined as the set of all points equidistant from a common center point. It is perfectly symmetrical, and its surface is uniformly curved, without any edges, vertices or faces. It is the shape made when a semi-circle is rotated around its diameter.
Half 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."
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.
One way to draw a sphere is to draw a circle and shade it with a crayon. You need a sheet of paper, a crayon, a pencil, a cotton ball, an eraser, a compass and a drawing board to accomplish this task.
The four spheres of the Earth are the atmosphere, the biosphere, the hydrosphere and the lithosphere. Each of these spheres is considered by scientists as interconnected in a greater geosphere that harbors all terrestrial life and materials.
A sphere has no faces. A sphere is defined as a round symmetrical object, while a face is defined a flat surface of an object. By definition a sphere does not have any faces.
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.
A sphere can be made out of paper by using origami techniques to fold the paper several different ways and pushing it out to make it appear as a spherical shape. It is a moderately easy origami project.
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.
