Description for Correct answer:
Area of square = 64 sq cm

\( \Large (Side)^{2} \)= 64

Side = \( \Large \sqrt{64} \) = 8 cm

According to the question,

=> \( \Large 2\pi r=4\times 8 \) => r=\( \Large \frac{4\times 8}{2\pi}=\frac{16}{\pi} \)

Area of the circle

=\( \Large \pi \times 16/ \pi\times 16/ \pi=\frac{256}{\pi} \)sq cm.
