### Sphere

A sphere is the three-dimensional geometric figure generated by the full rotation of a semicircle on its diameter.

Elements of a sphere:

• Center: Interior point equidistant from any point of the sphere;

• Radius: distance from the center to any point on the spherical surface;

• Chord: straight line segment connecting two points on the spherical surface

• Diameter: straight line segment joining two points on spherical surface, which passes through the center;

• Poles: points of intersection of the vertical rotation axis with the spherical surface.
