Circles are simple shapes of Euclidean geometry. A circle consists of those points in a plane which are at a constant distance, called the radius, from a fixed point, called the center.
The circumference of a square whose sides have length t is
C = 2 x pi x r, pi = 3.1415926535
And the area is
A = pi x r^2, pi = 3.1415926535.
