Given ;
- r = 56cm
Thus circumference of the circle = C = 2πr
- C = 2πr
- C = 2 × 22/7 × 56
- C = 2 × 22 × 8
- C = 44 × 8
- C = 352 cm
Since te same wire which was bent into a circle is bent into a square of side s cm.
Therefore;
- Circumference of the circle = Perimeter of the square
- 352 = 4s
- s = 88cm
Thus area enclosed by the square is given by ; A = s². (not of the square)
- A = (88)²
- A = 7744 cm²
