WebPi (π) is a special mathematical constant; it is the ratio of circumference to diameter of any circle. where C = π D. C is the circumference of the circle. D is the diameter of the circle. For example: If the radius of the circle is 4cm then find its circumference. Given: Radius = 4cm. Circumference = 2πr = 2 x 3.14 x 4 = 25.12 cm. Also, check: WebMar 14, 2024 · Therefore, we can derive a circle's circumference C from its diameter d using the following famous formula: C = πd (or C = 2πr using radius r). While it is impossible to overstate the significance of π in its fundamental and legendary role of being a constant representing the circumference/diameter ratio, its usage for area and volume ...
