Answer 1

Resposta:

A=π$R^{2} =3,14.8^{2} =3,14.64=200,96cm^{3}$

Explicação passo a passo:

Answer 2

$\Large\displaystyle\text{ \begin{gathered} \bf{ F\acute{o}rmula:} \end{gathered} }$

$\Large\displaystyle\begin{gathered} \sf{ A=\pi\cdot r^2} \end{gathered}$

$\Large\displaystyle\begin{gathered} \bf{ Dados:} \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \sf{ \begin{cases}\sf A=?\,cm^2\\\sf \pi=3{,}14\\\sf r=8\,cm\end{cases}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \bf{ Soluc_{\!\!,}\tilde{a}o:} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{A=3{,}14\cdot8^2 } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{A=3{,}14\cdot64 } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \therefore\green{\underline{\boxed{\boxed{\sf{A=200{,}96\,cm^2}}}} }~~(\checkmark) \end{gathered} }$
