Imagine rolling that square of paper into the cylinder. The top side of the square will be the same as the circumference of the circle once you form the cylinder. If the circumference of the circle is 4, then we can simply solve C = 2Ï€r = 4 --> r = 2/Ï€. From there, it's just plug and chug with the cylinder formula.AAPL wrote:

The OA is A.
I know that the volume of a cylinder can be determine by,
$$A_{cylinder}=\pi\cdot r^2\cdot h$$
But, I don't know how can I get the value of r.
I appreciate if any expert explain this PS question for me. Thank you so much.
volume of the cylinder = (Ï€)(radius)^2(height)AAPL wrote:
