Question

Plx answer Find the exact volume of the cylinder.

Answer 1

if the diameter of the cylinder's base is 8, then its radius is half that, or 4.

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=4\\ h=8 \end{cases}\implies V=\pi (4)^2(8)\implies V=128\pi$

Answer 2

the answer is B) 128
