A square of area 64 m² is made of wire. The wire is then bent to form a circle. Find the area of the circle?
- 81.5 m²
- 128 m²
- 201 m²
- None of these
Explanation
Square area 64 m² → side = 8 m → wire length = 4×8 = 32 m
Wire becomes circle → circumference = 32 m
2πr = 32 → r = 16/π
Area = πr² = 256/π ≈ 81.5 m²
