SUMMARY
The volume of a cylinder can be expressed as v = A² / (4πh), where h represents the height of the cylinder and A denotes the area of the original paper used to form the cylinder. This relationship is derived from the standard volume formula v = πr²h by manipulating the area of the paper, A = 2πrh, and substituting it into the volume equation. The discussion emphasizes the importance of understanding the geometric relationships and transformations involved in deriving these formulas.
