A steel wire, when bent in the form of a square, encloses an area of 121 cm2. The same wire is bent in the form of a circle. Find area the circle. Area of a square = ( Side )2 Now, ⇒ 4 x Side = Perimeter of a circle ⇒ 4 x 11 = Perimeter of a circle ⇒ Perimeter of a circle = 44 cm ⇒ 2πr = 44 ....( r is radius of a circle ) ⇒ r = `44/[2π] = 44/[ 2 xx 22/7]` = 7 cm ∴ Area of a circle = πr2 = `22/7 xx 7 xx 7 = 154 "cm"^2` Is there an error in this question or solution?
