MHB Variable Pi Formula: Diameter (mm) Calculation

AI Thread Summary
The variable pi formula for calculating diameter in millimeters is expressed as Diameter (mm) = 0.0000003 : (pi of D - 3.1416)^2, with pi of D ranging from 3.1416 to 3.1589. When pi of D equals 3.1416, the diameter approaches infinity, while at 3.1589, the diameter is 0.001 mm. A specific case shows that when pi of D is 3.14161, the diameter is 3000 mm. The formula highlights the sensitivity of diameter calculations to small changes in the value of pi. Understanding this relationship is crucial for precise measurements in applications requiring variable pi values.

variable pi formula
Diameter (mm) = 0.0000003 : (pi of D - 3.1416 )^2

Pi of D is variable from 3.1416 to 3.1589
Pi min = 3.1416
Pi max = 3.164

When pi of D = 3.1416 , D = infinite mm
When pi of D = 3.1589 , D = 0.001mm
When pi of D = 3.14161 , D = 3000mm

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
