As pi is the ratio of the ratio of the circumference (C) of any circle to its diameter (d), the circumference of a circle in terms of pi is: C = pi x d The circumference of a circle is pi times its diameter or 2 pi times its radius (since a diameter is 2 times the radius).

pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
circumference in m= 5*pi
The circumference is 4pi
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
The circumference of a circle is 2 pi r, where r is the radius, or it is pi d, where d is the diameter.there is no circuference of pi. Circumference refers to the outer edges of circles
