A circle and a rectangle have the same perimeter. The sides of the rectangle are 18 cm and 26 cm. The area of the circle is (Take π = 22/7)
-
- 125 cm²
- 230 cm²
- 550 cm²
- 616 cm²
- 125 cm²
Correct Option: D
Using Rule 14,
2πr = 2 (18 + 26)
⇒ 2 × | × r = 44 × 2 | |
7 |
⇒ r = 14 cm
∴ Area of circle = πr²
= | × 14 × 14 = 616 sq. cm. | |
