Cylinder Calculator
Calculate cylinder volume, surface area, base area, and lateral area from radius and height locally in your browser.
Enter a radius and a height from 0 (exclusive) to 1000000000 to see the volume (πr²h), surface area (2πr(h + r)), base area (πr²), and lateral area (2πrh). The calculation runs locally in your browser; your values are not uploaded or stored.

Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What does the cylinder calculator show?
Enter a radius and a height from 0 (exclusive) to 1000000000. The calculator returns the volume (pi times r squared times height), the surface area (2 times pi times r times height plus radius), the base area (pi times r squared), and the lateral area (2 times pi times r times height). For example, radius 5 and height 10 give volume about 785.398163397, surface area about 471.238898038, base area about 78.5398163397, and lateral area about 314.159265359.
Which formulas does the cylinder calculator use?
It uses volume = pi x r^2 x h, base area = pi x r^2, lateral area = 2 x pi x r x h, and surface area = 2 x base area + lateral area, which equals 2 x pi x r x (h + r), where r is the radius and h is the height you enter.
Which inputs are accepted?
Enter a radius and a height greater than zero through 1000000000. Decimal values are accepted. Zero, negative numbers, non-numeric text, and values above the limit show a clear error instead of a result.
Do my numbers stay private?
Yes. The calculation and copy action run locally in your browser. CodeASystem does not upload or store the values you enter.
