Cilindrico

Cilindrico is an adjective used to describe objects or shapes that have the form of a cylinder or relate to cylinders. In geometry, a cylinder is generated by moving a straight line parallel to a fixed direction along a base curve, producing two parallel, congruent bases connected by a curved surface. When the bases are circles and the line is perpendicular to them, the figure is a right circular cylinder; if the line is oblique, the shape is an oblique cylinder. Cylinders can be solid or hollow (a tube or pipe).

In mathematical terms, a right circular cylinder with radius r and height h has a volume V = π r^2 h. The lateral surface area is L = 2π r h, and the total surface area is SA = 2π r(h + r). For oblique cylinders, the same base area and height relations apply for volume, but the lateral surface area depends on the degree of obliqueness and is not given by the simple formula used for right cylinders.

Cylindrical shapes are ubiquitous in everyday objects and engineering. They appear in storage tanks, pipes, cans, batteries, architectural columns, and various mechanical components. In manufacturing, cylindrical tolerances and finishes are routinely specified to ensure proper fit, sealing, rotation, or load-bearing properties. The concept of cylindricity also informs computer-aided design and quality control processes.

Etymology and usage: the term cilindrico (and its variants in related languages) derives from Greek kylindros and Latin cylindrus, reflecting the classic cylindrical form. Today it is used across science, engineering, design, and education to denote objects with a circular cross-section extended along an axis.
