Circle Geometry Guide

Understanding circle properties is fundamental in geometry, engineering, and physics. Circles are perfect geometric shapes with constant curvature and unique mathematical properties.

Circle Formulas

Diameter = 2 × Radius
Circumference = 2π × Radius = π × Diameter
Area = π × Radius²
π ≈ 3.14159265359

Pi (π): The ratio of a circle's circumference to its diameter, approximately 3.14159. This mathematical constant appears throughout mathematics and physics.

Applications: Circle calculations are essential in engineering (pipes, wheels, gears), architecture (arches, domes), astronomy (planetary orbits), and manufacturing (circular components).

Sector and Arc: Parts of circles have their own formulas. Arc length = (θ/360°) × 2πr, and sector area = (θ/360°) × πr² where θ is the central angle in degrees.
