Answer 1

Answer:



Step-by-step explanation:

V=$\pi r^{2}$*H

V=3.14*4*4*8

V=401.92$in^{2}$

Answer 2

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=4\\ h=8 \end{cases}\implies V=\pi (4)^2(8) \\\\\\ V=128\pi \implies \stackrel{using~\pi =3.14}{V=401.92}$
