The area of the greatest circle inscribed inside a square of side 21 cm is (Take π = 22 7 )
-
- 344.5 cm²
- 364.5 cm²
- 346.5 cm²
- 366.5 cm²
- 344.5 cm²
Correct Option: C
Using Rule 14,
The diameter of the greatest circle inscribed inside a square will be equal to the side of square i.e., 21 cm.
∴ Radius of the circle = 21/2
∴ Area of the circle = π × (radius)²
| = | × | × | = | cm² | ||||
| 7 | 2 | 2 | 2 |
= 346.5 cm².
