    A circle’s perimeter is called the circumference. The symbol of the circumference is C.

    The Circumference (or) perimeter of a circle = 2πR

    where,

    R is the radius of the circle

    π is the mathematical constant with an approximate (up to two decimal points) value of 3.14

    Again,

    Pi (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
