Circumference of a Circle from Diameter
Formula:C = πd
Introduction to Circumference of a Circle from Diameter
The circumference of a circle is calculated by multiplying the value of π (pi) with the circle's diameter. In this formula, C represents the circumference of the circle, and diameter is the distance across the circle, passing through the center. The result is expressed in the same units as the diameter, such as inches, centimeters, or any other unit of length measurement.
Parameter usage:
diameter
: diameter of the circle
Example valid values:
diameter
= 7
Output:
circumference
= calculated circumference of the circle
Data validation
The diameter should be a positive number.
Summary
This calculator takes the diameter of a circle as input and outputs its circumference. It is not specific to a particular unit of measurement.
