What is the surface area of a cylinder?

Total SA = 2πr² + 2πrh. This covers: 2 circular ends (2πr²) + curved lateral surface (2πrh). Lateral SA only = 2πrh.

How is cylinder volume related to circle area?

A cylinder is essentially a stack of circles. Volume = (area of base circle) × height = πr² × h. This makes intuitive sense — the more circles stacked, the greater the volume.

What units does the volume come in?

Volume units are the cube of the length units used: cm³ (mL), m³, ft³, in³. Note: 1 litre = 1000 cm³ = 1000 mL.

Cylinder Volume Calculator

The Cylinder Volume Calculator computes the volume of a cylinder using the formula V = π × r² × h, where r is the radius and h is the height. Cylinders are everywhere in engineering and daily life — pipes, cans, tanks, and columns. Enter the radius and height to get the volume and lateral surface area instantly.

Frequently Asked Questions

V = πr²h, where r is the radius of the circular base and h is the height. The formula comes from multiplying the base circle area (πr²) by the height.
