i need help with this, im not hood at algebra and im not sure about this.

Given data:
The diamter is equal to height of the cylinder D=H=S.
The expression for the Volume of the cylinder is,
[tex]V=\frac{\pi}{4}D^2H[/tex]Substitute the given values in the above expression.
[tex]\begin{gathered} V=\frac{\pi}{4}(S)^2S \\ =\frac{\pi}{4}S^3 \end{gathered}[/tex]Thus, the volume of the cylinder is πS^(3) /4.
