The area of a circle 1cm in diameter is determined by the formula Pi x Radius x Radius. Radius is 5mm Pi is 3.14159 (roughly) So the area is 3.14159 x 5 x 5 Which is 78.5398163397448 square mm.
2 x pi x 2 = 4 x pi
Area = (pi) x (Radius)2Radius = sqrt(area/pi)Circumference = (2 pi) x (Radius) = (2 pi) x sqrt(area/pi)Circumference = 2 x sqrt(pi x area)
Divide that by pi to get the diameter, or by (2 x pi) to get the radius.
If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.If you mean a circle: the circumference is equal to diameter x pi, or 2 x pi x radius.

-- enter the diameter of the circle-- hit the big ' X ' for "times"-- enter (pi) with the pi button-- touch " = " ('equals')The circumference is displayed.
I'm not sure, but that would make one big pi. <groan> Diameter x pi = circumference 27 ft x 3.141 = ___
x(pi+1)/(pi+1)
Circumference = (2) x (pi) x (Radius)= (2 pi) times (X + 4)= same as (2 pi X) + (8 pi)= same as [ pi (2X + 8) ]
The area of a circle 1cm in diameter is determined by the formula Pi x Radius x Radius. Radius is 5mm Pi is 3.14159 (roughly) So the area is 3.14159 x 5 x 5 Which is 78.5398163397448 square mm.
