Identify the radius (r) and/or diameter (d) of the cylinder
If given diameter, compute radius: (r=frac{d}{2})
Measure or identify the height (h) of the cylinder
Use the volume formula: (V=pi r^2 h)
Compute (r^2), multiply by (h), then multiply by (pi)
Report the result in cubic units (e.g., (text{cm}^3), (text{m}^3))
