Circle Kit
Product Code : JA-MLI-1741
The Circle Kit (SKU JA-MLI-1741) is a set of three circular discs with different radii for exploring the relationship between radius, diameter and circumference. Pupils roll each disc along a flat surface through one full turn, measure the length it covers and compare that circumference with the diameter of the same disc. Doing this for three sizes shows that the ratio stays the same, which leads to the value of pi. JaincoLab makes this circle circumference kit in Ambala, India.
Specifications
The kit contains three circular discs, each with a different radius, for measuring circumference by rolling; the disc radii, material and thickness are not listed and are confirmed on the quotation.
