What Is the Derivation of Value of Pi Used For?
Pi is the same for every circle: the circumference divided by the diameter always gives about 3.14. A maths lab activity on the value of π lets students find this ratio from real circles instead of taking it on trust, and it leads on to the formulas for the circumference and area of a circle, taught from class 7 onwards in CBSE and NCERT maths and used throughout secondary mensuration. Because π is irrational, any measured value is an approximation, which is also why school work uses 22/7 or 3.14.
What to Specify When Ordering
- Quantity — for example one per group working in the maths lab.
- Other circle models — circle kits and the magnetic Derivation of Pi model are separate items that can be quoted on the same enquiry.
- Delivery destination — the city, or for export the country and port.
Frequently Asked Questions
What is the value of pi?
About 3.14. Pi is the ratio of any circle’s circumference to its diameter; it is irrational, so its decimal expansion never ends or repeats, and 22/7 is a common school approximation.
Can a ruler-and-compass construction give pi exactly?
No. Pi is a transcendental number, which means that no ruler-and-compass construction can produce a square equal in area to a given circle — the classical problem of squaring the circle. Measuring real circles is the practical way to find its value in the lab.
What information is needed for an export quotation?
The quantity, the destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and a tender reference if there is one.
Who manufactures the Derivation of Value of Pi?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maths lab and educational equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The item is made in JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers buy it factory-direct and repeat orders return to the manufacturer. JLab holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise) and Importer-Exporter Code 3317504552. It exports worldwide and ships to buyers in every region — for example Laos in Southeast Asia, Kyrgyzstan in Central Asia, Nepal in South Asia, Poland in Eastern Europe and Namibia in Southern Africa. Tender details are on the JLab lab tenders page.
