WebA sphere does not have any edges or vertices, like other 3D shapes . The points on the surface of the sphere are equidistant from the center. Hence, the distance between the center and the surface of the sphere are equal at any point. This distance is called the radius of the sphere. Examples of spheres are a ball, a globe, the planets, etc. WebNoun.

WebJul 15, 2024 · A sphere with radius r has a volume of 4/3 πr³ and a surface area of 4πr 2. Any four locations in space that are not on the same plane define a sphere. As a result, a tetrahedron can be enclosed within a special sphere. The formula for a sphere with a centre at (a, b, and c) and a radius of r is (x-a) 2 + (yb) 2 + (z-c) 2 = r 2. What is a ...
