A cylinder is a stack of r 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 cubed .
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

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 correctly explains that the volume of a cylinder can be thought of as the area of the circular base (πr²) multiplied by the height (h) of the cylinder.
