WebA sphere (from Ancient Greek σφαῖρα (sphaîra) 'globe, ball') is a geometrical object that is a three-dimensional analogue to a two-dimensional circle.A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the centre of the sphere, and r is the sphere's radius. The earliest known mentions of … WebWe can now generalize the notion of open and closed intervals from to open and closed sets in . (Open and Closed Sets) A set is open if every point in is an interior point. A set is closed if it contains all of its boundary points. Determine if the following sets are open, closed, or neither. The set is openclosedneither open nor closed .
