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.
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
The Earth's four spheres interact in all six possible combinations: lithosphere and hydrosphere, lithosphere and biosphere, lithosphere and atmosphere, hydrosphere and biosphere, hydrosphere and atmosphere, and biosphere and atmosphere. All six interactions go in both directions, for example, from l
The sun and planets follow the ecliptic, an imaginary plane in the celestial sphere tilted approximately 23.5 degrees relative to the celestial equator. Earthbound observers see the sun and planets move along the ecliptic arc, rising up from the east and setting in the west.
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.
The hydration sphere, a form of solvation shell, is a chemical structure that surrounds a solute in a solution in which the solvent is water. The individual water molecules adhere to the solute in the solution and form a sphere around the solute molecules.
While iron and nickel form the liquid outer layer of Earth's core, the solid inner core is made mostly of iron. The iron in Earth's core is what gives the planet its magnetic field.
According to scientists, the earth is about 4.5 billion years old. However, because of the constant upheavals in climate, plate tectonics, asteroid strikes and other events, most of the evidence of the earth's beginnings are lost.
The moment of inertia of a sphere is I = 2/5 MR^2 for a solid sphere and I = 2/3 MR^2 for a thin spherical shell. This moment of inertia can be derived from the moment of inertia of a thin disk by summing the moments of inertia of a series of infinitely thin disks throughout the volume of the sphere
Scientists estimate that the Earth was created approximately 4.54 billion years ago, which is less than 100 million years after the formation of the solar system. It is thought that the planet was created as a result of more than 10 different collisions between various celestial bodies.
