In Mathematics (Geometry), 'Radius' is a foundational concept when studying circles and spheres. Understanding its Hindi term is essential for Hindi medium students.
The plural of radius is 'radii' (उच्चारण: रेडिआई). In Hindi, the plural form is त्रिज्याएँ (Trijyaein).
Radius = त्रिज्या (Trijya)
A radius is a straight line from the center to the circumference of a circle or sphere.
Example:
| English Term | Hindi Meaning |
|---|---|
| Circle | वृत्त (Vritta) |
| Center | केंद्र (Kendra) |
| Diameter | व्यास (Vyas) |
| Circumference | परिधि (Paridhi) |
| Chord | जीवा (Jiva) |
The relationship between Radius (त्रिज्या) and Diameter (व्यास) is: Diameter = 2 × Radius (व्यास = 2 × त्रिज्या)
Radius is half of the diameter. So, Radius = 14 / 2 = **7 cm**.
