📖 About Sphere
A sphere is a geometric shape consisting of all points in space that are at a fixed distance (radius) from a fixed point (center). Sphere is a perfect geometric shape widely existing in nature and daily life, such as the Earth, basketballs, water droplets, etc.
Sphere Features:
- The distance from any point on the sphere to the center is equal (equal to the radius)
- Sphere has the maximum volume among shapes with the same surface area
- Sphere has no edges or vertices
- The cross-section of a sphere is a circle
