If we define the radius of a square to be the distance from the center of the square to one of the vertices (corners) you can compute the radius.
A square with sides of 1 will have a radius of √2/2
A square with sides of 's' will have a radius of (s * √2/2)
One definition of radius: "A line segment that joins the center of a regular polygon with any of its vertices."
The area of a circle is π (Pi) times the Radius<span> squared: A = π × r</span>2. Or, when you know the Diameter: A = (π/4) × D2<span>.</span>
