Can I find the radius if I only know the volume and height?

Yes, the calculator supports eight different radius formulas, including one that uses volume and height. Select the appropriate input combination from the available options.

What is the formula used when I enter height and lateral surface area?

The calculator uses the formula r = sqrt((A - πh) / (2π)), where A is the lateral surface area and h is the height, to compute the radius.

Does the calculator handle oblique cylinders?

No, the tool is designed for right circular cylinders, where one base lies precisely above the other. Oblique cylinders are not supported.

How can I share my calculation results?

The calculator includes a 'Share result' button that allows you to export or save the computed radius and other cylinder parameters for later use or collaboration.

About this tool

What Radius of a Cylinder Calculator does

The Radius of a Cylinder Calculator on Omni Calculator determines the radius of a right circular cylinder when given its height and lateral surface area. Users input the height and lateral surface area, and the tool instantly computes the radius using the formula r = sqrt((A - πh) / (2π)). The result provides the missing dimension needed to complete the cylinder's geometry. The site also offers eight different radius formulas, allowing users to solve for the radius using various combinations of height, volume, diagonal, base area, lateral area, total area, or surface-to-volume ratio, making it versatile for different problem types. The interface is straightforward, presenting input fields and results clearly alongside related cylinder metrics like volume and surface area. Compared to other tools for this task, Omni Calculator’s version stands out by offering multiple formula options within a single calculator, rather than requiring separate calculations for different given values. It also provides contextual explanations of cylinder terminology and related concepts, helping users understand what they are calculating beyond just the numeric result. The clean layout and ability to share or clear results add practical convenience for quick problem-solving.
