To find the length (circumference) of a circle given its diameter, use the formula: Circumference = π * Diameter. Simply multiply the diameter of the circle by π (approximately 3.14159). For example, if the diameter is 10 units, the circumference would be 31.42 units (10 * 3.14159). This formula is straightforward and universally applicable.
