Calculate a closed right circular cylinder
Enter radius and height to calculate volume, total surface area and curved lateral surface area. The total includes both circular ends, while the lateral result isolates the curved side. This distinction is useful when comparing container capacity with label coverage, paint area or a geometry assignment that asks for a specific part of the solid.
Match the ideal solid to the physical object
The model assumes perfectly circular ends, a perpendicular axis and a fully closed cylinder. Open containers need one end removed from surface area, while wall thickness changes usable internal volume. Use the same length unit for radius and height, verify whether a drawing gives radius or diameter, and handle seams, headspace and material allowances separately.
Frequently asked questions
Does total surface area include both ends?
Yes. It includes two circular bases and the curved side.
How do I use a diameter?
Divide the diameter by two before entering the radius.
Is wall thickness included?
No. The result describes an ideal geometric cylinder.
