Key Properties of a Sphere:- Center (O) – The fixed point from which all surface points are equally distant.
- Radius (r) – The constant distance from the center to any point on the sphere.
- Diameter (d) – Twice the radius (d = 2r), the longest straight line passing through the center.
- Surface – The set of all points at distance exactly r from the center.
