Thread: the circumference of the square

1- Write C++ program that compute the circumference of the square in this drawn shape. The program asks the user to enter the area of the circle.

Note: that the input must entered in meter and then the circumference should be displayed in centimeter.

1. Area of the circle: A = Pi * (r*r)
2. Side of the square: L = 2*r
3. Circumference of the square: C = 4*L

that's pretty much everything you'll ever get from this forum if you don't post your own code.

btw:

C = 4*L = 4*2*r = 8*r = 8 * sqrt(A / Pi)
