Circular bodies

Circular bodies are three-dimensional solids whose boundaries include circles or are generated by rotating a line or curve around an axis. The main types are spheres, cylinders, and cones.

Important properties

• Spheres have all points on the surface at the same distance from the center.

• Cylinders have two parallel, congruent circular bases and a curved surface.

• Cones have a circular base and a curved surface that tapers to a point (the apex).

• Volumes and surface areas of these bodies can be calculated using specific formulas.
