Question

a wire is in a corcular shape of area 5544cm2. if the same wire is bent in the shape of a square, find the length of the side of a square and its area.​

Answer 1

$Area \: of \: Circle = \pi \: {r}^{2}$

$\pi \: {r}^{2} = 55544$

$r = \sqrt{5544 \times \frac{7}{2} }$

$r = 42 \: cm$

$Length \: of \: Wire = Perimeter$

$2\pi \: r = 2 \times \frac{22}{7} \times 42$

$= 264 \: cm$

$Area = 4,356 \: {cm}^{2}$
