Step-by-step explanation:

We know by different of squares, (x-y)(x+y)=74. Since we need to find the smallest possible answer for x+y, we let x+y=2, where both x and y = 1.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius=\frac{diameter}{2}\\
h=height\\
----------\\
diameter = d\\
r=\frac{d}{2}
\end{cases}\implies V=\pi \left( \frac{d}{2} \right)^2 h
\\\\\\
V=\pi \left( \frac{d^2}{2^2} \right)h\implies V=\cfrac{\pi d^2 h}{4}\implies 4V=\pi d^2 h\implies \cfrac{4V}{\pi d^2}=h$
