Here's a guess... Without getting overly complicated.... The diameter of the atom isn't just the diameter of the atom's nucleus... it is the diameter of the whole atom including the electron cloud surrounding the nucleus. As the name implies, an electron cloud represents all the possible locations that the electron could be. This cloud has thickness and therefore the atom could be smaller if the electron is in a portion of the cloud closer to the nucleus or larger is the electron is in a portion of the cloud farther from the nucleus. The "known value" is probably just the average of the two. Therefore, an atom's diameter has a range rather than a fixed value.
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
Half a diameter is known as the radius.
The radius is half the diameter, so divide the diameter by 2.
The half of a diameter of a circle is known as a radius.
If a line segment touches two points on the circle it is called as: 1. secant; if the line extends outside the circle. 2. chord; if the line is present only within the circle. Diameter is a line which satisfies the second condition hence it is a chord. The additional condition for a chord to be known as diameter is that the chord should pass through the center of the circle!

The radius of a circle is the distance from the center of the circle to the outer edge Also known as half of the diameter. The diameter is the distance from opposite edges of the circle going through the centre.

hdheheh
the diameter of a willow tree is not known on the computer.
The radius is half the diameter, so divide the diameter by 2.
The half of a diameter of a circle is known as a radius.
The diameter is the circumference divided by pi. (3.14159...)
standard normal distribution
Diameter = circumference/pi where pi is 3.14159 (approx)
