Question

a wire bent in form of a square, encloses an area of 196 square m . if the same wire is bent to form a circle , find the area of the circle

Answer 1

Answer:

249.5m²

Step-by-step explanation:

Area of a square= 196 metre²

a²=196

a=√196

a=14m

Perimeter of the square= 4a= 14x4=56m

Perimeter of square = Circumference of circle

2x22/7xr=56

r= 56x7/2x22=8.90m

Area of a circle= 22/7x8.91x8.91= 249.505m²
