Essa e urgenteeeeeeeeee​

Answer 1

Resposta:

$6) \: 3600 π \: {cm}^{3} \\ 7) \: 920 π \: {cm}^{2}$

Explicação passo-a-passo:

$6) \\ volume = π \times r {}^{2} \times h \\ volume = \: π \times 100 \times 36 \\ volume = 3600π \: cm {}^{3} \\ \\ \\ \\ 7) \\ \: area \: da \: base = \: π \times {r}^{2} \\ = \: π \times 10 {}^{2} \\ 100\: π \\ \\ area \: lateral = \: π \times d \times h \\ = \: π \times 20 \times 36 \\ = 720\: π \\ \\ area \: total = (area \: da \: base)2 + area \: lateral \\ =( 100\: π)2 + 720\: π \\ 200\: π + 720\: π \\ 920\: π \: cm {}^{2}$
