Typical answer from The WikiAnswers Community: IT IS WRONG!
The diameter is the distance across the circle, through its centre. It is double the radius, not the other way round!
The circumference of a circle with a diameter of 7.2 is 22.62. (rounded)
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
The circumference of a circle with a diameter of 1 cm would be 0.31. This is used a lot in math.
The cord of a circle that contains the center of that circle is a diameter of that circle.
You do a diameter circle!!

If you mean a circle area than A = 63.61725 inch². Area A = pi times diameter² / 4.
The cord of a circle that contains the center of that circle is a diameter of that circle.

If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
A circle with a diameter of 28 is a circle.
The circumference C = diameter d times pi. C = 9 times 3.14159 = 28.274334 for a circle of 9 units You have only to choose for the circumference and for the diameter the same unit. Then it work for meters, centimeters, inches, and marsian bobugs,
The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.
Diameter of a circle = circumference/pi Diameter of a circle = 2*radius
Diameter of a circle = 2*radius Diameter of a circle = circumference/pi
