blow ratio is the ratio of mold diameter to the preform diameter.

If you only have a given diameter you have to multiply the diameter by Pi (3.142) or 3.14 and then you get the circumference!
It is: pi*diameter
Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
the radius is half the diameter
The radius is half the diameter.
Radius = Diameter/2.
Divide the diameter by 2.
3.14 times the diameter
Given only the lateral area, you cannot determine the diameter.
