A cyclindrical water tank has a radius of 6 feet and a height of 20 feet. A larger tank with the same height has a volume that i

xz_007 [3.2K]

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=6\\
h=20
\end{cases}\implies V=\pi 6^2(20)\implies \stackrel{\textit{smaller cylinder}}{V=720\pi }$

since the smaller tank has a volume of 720π, then the larger tank has a volume of 3 times that much or 3*720π, or 2160π, and its height is the same as the smaller one's, 20.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
V=2160\pi \\
h=20
\end{cases}\implies 2160\pi =\pi r^2(20)\implies \cfrac{2160\pi }{20\pi }=r^2
\\\\\\
108=r^2\implies \sqrt{108}=r\implies 6\sqrt{3}=r
\\\\\\
\stackrel{\textit{and since the \underline{d}iameter is twice the radius}}{d = 2r\implies d=12\sqrt{3}}$
