Make any chord for this circle and then construct it's perpendicular bisector; this line will lie on top of the diameter. Finally, just measure the part inside the circle to get the diameter.

2 x radius will find the MEASUREMENT of a diameter.
Tooyoufou failed basic Geometry.
Kommision also failed Math. The first formula gives you area. Second one gives you circumference. Neither one will give you diameter.

It depends what you are given... If you know the radius, then you just double it... If you know the circumference, you divide by pi...
If you have an inscribed square, you use pythagorean's theorem to give yourself the diameter as L times the square root of 2.
