Cylinder measurements figure A cylinder projection with top and bottom ellipses, radius, and vertical height marked.

Enter valid values to draw the figure.

r = radius · h = height · S = surface · V = volume

The circular radius and perpendicular height determine the cylinder's surface and volume.

FAQ

How do I use the Cylinder Calculator?

Open the Cylinder Calculator, fill Radius (r) and Height (h), and read the result. Enter Radius (r) and Height (h) for the Cylinder Calculator; use finite values in the indicated domain. The calculator reports Surface and Volume: Cylinder volume πr²h and total surface 2πr(r+h). Radius and Height must share a length unit; area and volume use its square and cube.
