Question

Calcule o volume de um cilindro cuja altura mede 25 cm e o diâmetro da base mede 8,4 cm. Utilize o valor de 3,14 para π. ​

Answer 1

$\large\boxed{\begin{array}{l}\sf dados\begin{cases}\sf h=25\,cm\\\sf d=8,4\,cm\longrightarrow r=4,2\,cm\\\rm V=?\end{cases}\\\underline{\sf soluc_{\!\!,}\tilde ao\!:}\\\rm V=\pi\cdot r^2\cdot h\\\rm V=3,14\cdot4,2^2\cdot25\\\rm V=1384,74\,cm^3\end{array}}$
