The circumference. Although it isn't exactly 3. It is actually pi (3.14159265...) Which goes on and on forever.
As big as your but suckers!

An infinite number
Apparent (visual) diameter of the [full] moon . . . . always near 1/2 degree. Angle from horizon to zenith . . . 90 degrees . . . roughly 180 apparent moon diameters.
There are infinite amount of diameters.
No, all chords are not diameters, though all diameters are chords.
The ratio of the diameters are the cube root of the ratio of the volumes. Therefore the diameter ratio is 3 to 5. 33 = 27 53 = 125
There are infinite diameters within a circle.
A diameter is a cord in a circle containing the center of the circle. But some circles are sections of spheres. Not all diameters are diameters of spheres.
This question does not make sense. All chords are not, in fact, diameters. Actually, only chords that pass through the center of a circle are diameters.
To convert centimeters to inches, divide by 2.54.
STP diameters are restricted by convergence times.
