Circle Manufacturer, Suppliers and Exporter in India
Jaincolab Manufacturers is leading Circle Manufacturer,and supplier and Exporter in India
JaincoLab Circle kits help secondary students work out radius, diameter and area relationships by hand rather than from diagrams. The Circle Kit (JA-C-3647) supplies three disks of different radii for comparison, and the plastic Magic Ring measures 25 cm outside and 20 cm inside, with holes at set distances. A Derivation of Circle Area model completes the range for mensuration lessons.
Last updated: October 2026.
What is Circle?
The Circle range covers hands-on mathematics manipulatives used to teach circle geometry — kits with disks of different radii for comparing measurements, and ring-based models that let students physically derive relationships such as the area of a circle by comparison with a rectangle of equal area.
Selected Circle — Model Numbers and Specifications
| Model / Product Code | Product | Description |
|---|---|---|
| JA-C-3647 | Circle Kit | Kit provided with a set of three circular disks of different radii for hands-on radius and diameter comparison. |
| JA-C-3649 | Magic Ring | Circular plastic ring, outer dia. 25 cm and inner dia. 20 cm, with holes at set distances for geometry demonstrations. |
| JA-C-3653 | Derivation of Circle Area | Manipulative used to demonstrate that the area of a circle equals the area of an equivalent rectangle. |
Applications
| Setting | Use |
|---|---|
| Secondary geometry labs | Hands-on demonstration of circle area, radius and diameter relationships |
| Mensuration teaching | Deriving area formulae by direct comparison rather than by rote |
| School and tender procurement | Bulk circle-geometry kits for institutional mathematics lab setups |
Frequently Asked Questions
Is the Circle range different from the Theorems range in your catalog?
Yes. Circle covers radius, diameter and circle-area manipulatives specifically, while Theorems covers a broader set of geometry and mensuration models including Pythagoras theorem demonstrations and conic sections.
How does the Derivation of Circle Area model work?
The Derivation of Circle Area manipulative (JA-C-3653) demonstrates that the area of a circle equals the area of an equivalent rectangle. Students reach the area formula by direct comparison rather than by rote.
