The circumference is 4pi
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
By using the well-known formula, A = pi x r2, and expressing the radius in terms of the circumference, r = c / (2 x pi). Replace in the first formula, and simplify. f
