Cylinder Calculator

Calculate the volume, surface area, and lateral area of a cylinder by entering radius and height. Ideal for students, engineers, and designers online.

cylinder radius height calculator

A Cylinder Calculator assists the user to be in a position to find the volume, surface area, and lateral area of a cylinder on any given radius and height of the cylinder by entering the height and radius of the cylinder. It suits well in education, engineering, and design applications, and it gives instant and accurate calculations.

cylinder surface area calculator

The Cylinder Calculator is an online tool that computes the volume, surface area, and lateral area of a cylinder using its radius and height. By entering these dimensions, the calculator instantly provides accurate results using standard formulas:

\[ Volume = \pi r^{2}h, \textrm{Lateral Area} = 2\pi rh, \textrm{Surface Area} = 2\pi r(r +h) \]

This tool is useful for students, engineers, architects, and designers who need precise cylinder measurements for math problems, construction, or design tasks. The interface is simple, responsive, and requires no installation, delivering instant results while reducing manual calculation errors.

Work, Installation, Input to Outpu

Work:

  • Accepts cylinder radius and height as input.
  • Calculates volume, lateral area, and surface area using formulas.
  • Displays results instantly.

Installation: No installation required; works in any modern web browser.

Input:

  • Radius r
  • Height h

Output:

  • Volume
  • Lateral area
  • Surface area

Testing and Final Adjustments

Check radius and height values with different radius and height values, including decimals. Checker Checks manually using formulas. These should be invalid input, such as negative numbers or zero. Properly rounds off to the decimal. Mobile and desktop responsiveness of the test. Give real-time updates whenever there is a change in input. Present results in a clear and unitary way. There should be an optional visual diagram of the cylinder, which changes with radius and height.
