The area of a given square wire that is bent is 100 cm². Find the circumference of the circle that is made from the same wire when re-bent.
A: 30.31cm
B: 10cm
C: 5.64cm
D: 35.45cm
The Area of the two shapes will be equal. so hence area of circle = 100 cm²
Area = πr²
100 = (22/7) × r²
Radius = 5.64 cm
we, use thr radius to get the circumference of the circle
Circumference = 2πr
Circumference = 2 × (22/7) × 5.64
C = 35.45 cm
