Question

O volume do cilindro abaixo, é igual a:

A) 43,15 m³
B) 74,43 m³
C) 50,24 m³
D) 54,16 m³
E) 134,26 m³

Answer 1

$\large\boxed{\begin{array}{lr} \sf{volume~do~ cilindro}\end{array}}$

$\boxed{\begin{array}{lr}V = \pi \: . \: r {}^{2} \: . \: h \\V = 3,14 \: . \: 2 {}^{2} \: . \: 4 \\ V = 3,14 \: . \: 4 \: . \: 4 \\V =12,56 \: . \: 4 \\ \boxed{V = \red{50,24 \: m {}^{3} }} \end{array}}$

$\large\boxed{\begin{array}{lr} \boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{ \huge\blue{ opc_{\!\!,}\tilde{ao}~(C)}}}}}}}}\end{array}}$

Answer 2

$\large O ~volume ~do ~cilindro ~ \Rightarrow ~ V = 50,24~m^3\\\\\\\large Letra ~C) ~ 50,24~m^3$

                            $\large Volume ~de ~s\acute{o}lidos ~geom\acute{e}tricos$

$V = \pi~ . ~r^2~ .~ h\\\\V = 3,14 ~. ~2^2 ~. ~4\\\\V = 3,14 ~. ~4 ~. ~4\\\\V = 3,14 ~. ~16\\\\V = 50,24~m^3$
