Sphere

A sphere is a three-dimensional round object. Here, students will get an opportunity to learn a mathematical definition of a sphere, and discuss the formulas associated with spheres.

Definition of a Sphere

A sphere is a 3-dimensional geometrical figure that is completely round and circular - like a ball. Geometrically, a sphere is characterized as the arrangement of all points equidistant from a single point in space. The distance from an external point to the centre point of the sphere is the radius(r), and the longest straight line within a sphere is the diameter (d).
