...The diameter of a circle enters in two formulas. Length of Circumference: C=Pi*D (D diameter) ====>D=C/Pi Area of the disk A=Pi *D^2/4 =====>D=SQRT(4*A/Pi), SQRT is the square root

formula is simply this: C = (pi)d. In this equation, "c" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by
