Answer 1

✅ Formula :

✔Lado del cuadrado :

$64 = l {}^{2} \\ \sqrt{64} = l \\ 8 = l$

✔El radio :

$r = \frac{diametro}{2} \\ \\ r = \frac{8}{2} \\ \\ r = 4$

✔Despejemos :

$as = l {}^{2} - \pi(r) {}^{2} \\ as = (8) {}^{2} - \pi(4) {}^{2} \\ as = 64 -16\pi \\ as = 64 - 16(3.14) \\ as = 64 - 50.24 \\ as = 13.76m {}^{2}$

✅ El área es 13,76 m²
