Question
A copper wire is bent in the form of a square with an
area of 121 cm². If the same wire is bent in the form of a circle, the area of the circle will be: (Take π = 22/7)Solution
Area of square = a² = 121 => side a = 11 cm. Length of wire (Perimeter of square) = 4a = 44 cm. Circumference of circle = 2πr = 44. 2 × (22/7) × r = 44 44r/7 = 44 => r = 7 cm. Area of circle = πr² = (22/7) × 7 × 7 = 154 cm².
