Possible Answers:
A cylinder is a curved lateral surface with height h and two circular bases, each with area πr2 , so its volume formula is V=2πr2h . A cylinder is a curved lateral surface with height h and two circular bases, each with area pi r squared , so its volume formula is upper V equals 2 pi r squared h . A cylinder is a stack of h circles, each with an area of πr2 and a thickness of one unit, so its volume formula is V=πr2h . A cylinder is a stack of h circles, each with an area of pi r squared and a thickness of one unit, so its volume formula is upper V equals pi r squared h . A cylinder is a curved lateral surface with area 2πrh and two circular bases each with area πr2 , so its volume formula is V=2πrh+2πr2 . A cylinder is a curved lateral surface with area 2 pi r h and two circular bases each with area pi r squared , so its volume formula is upper V equals 2 pi r h plus 2 pi r squared . A cylinder is a stack of r circles, each with an area of πr2 and a thickness of one unit, so its volume formula is V=πr3 .

The statement that best describes an informal argument for the formula for the volume of a cylinder is:
"A cylinder is a stack of h circles, each with an area of πr² and a thickness of one unit, so its volume formula is V=πr²h."
This argument effectively explains that the volume of the cylinder can be thought of as the sum of the areas of circular cross-sections (each with area πr²) stacked up to a height h.
