Answer 2

Answer:

$\\\;\underbrace{\underline{\sf{understanding\;the\;question}}}$

• $circle \: of \: radius \: 4cm \: cut \: out \: from \: square \: piece.$
• $an \: aluminium \: sheet \: was \: in \: square \: whose \: area \: is \: 8 \: cm$
• $give \: \pi = 3.14$

$\\\;\underbrace{\underline{\sf{according\;to\;the\;question}}}$

$area \: of \: square \: = {a}^{2}$

$area \: of \: circle = \pi {r}^{2}$

$\underline\mathfrak\red{give:-}$

$area \: of \: square - area \: of \: circle$

$\pi {r}^{2} - {a}^{2}$

$3.14 \times 4 \times 4 - {8}^{2}$

$50.24 - 64$

$6.24$
