Círculos

Círculos are a fundamental geometric shape. A circle is defined as the set of all points in a plane that are at a fixed distance from a central point. This fixed distance is known as the radius. The plural form, "círculos," refers to more than one such shape.

Key properties of a círculo include its radius (r), diameter (d), circumference (C), and area (A). The diameter is twice the radius (d = 2r). The circumference is the distance around the edge of the círculo and is calculated using the formula C = 2πr or C = πd, where π (pi) is a mathematical constant approximately equal to 3.14159. The area enclosed by the círculo is given by the formula A = πr².

Círculos appear frequently in nature, art, and engineering. Examples range from the shape of planets and wheels to the design of clocks and the arrangement of elements in a mandala. The mathematical properties of círculos have been studied for centuries and are integral to various fields of mathematics and science. Understanding círculos is a foundational step in geometry.
