Answer» Correct Answer - Option 3 : 154 cm2 Given: Perimeter of the square = 44 cm Perimeter of square = Circumference of the circle Formula used: Circumference of the circle = 2πr Area of the circle = πr2 Calculation: As, Perimeter of square = Circumference of the circle ⇒ 44 = 2πr ⇒ r = 7 cm Area of the circle = πr2 ⇒ Area of the circle = (22/7) × 72 ∴ Area of the circle is 154 cm2 |
