Question

a wire is in a circle shape of radius 28cm. if it is bent in the form of square what will be the area of square formed

Answer 1

r=28 cm
Circumference = $\pi$r²
                        = 2464 cm
This is the length of the wire.
So it is also the perimeter of the square.
2464=4a
a=616 cm
Area = a²
         = 379456 cm²
