How the Cylinder Volume Calculator Works
A cylinder’s volume is the area of its circular base times its height: πr²h. Enter the radius and height and this calculator returns the volume in cubic units, plus the total surface area 2πr(r+h) and the base area πr².
It’s the go-to for round tanks, pipes, cans and columns. Keep radius and height in the same unit; the volume comes out in that unit cubed — convert cubic inches or feet to gallons or litres as needed.
volume = π × radius² × height
Frequently Asked Questions
How do you calculate the volume of a cylinder?
Multiply the area of the circular base (πr²) by the height: V = πr²h.
How many gallons is a cylinder?
Find the volume in cubic inches and divide by 231, or in cubic feet and multiply by 7.48, to get US gallons.
What is the surface area of a cylinder?
2πr(r+h) — the two circular ends plus the curved side.
