Cylinder Volume Calculator

Enter a cylinder's radius and height to find its volume, lateral surface area, total surface area and base area using the exact geometry formulas.

How to find the volume of a cylinder

  1. Enter the base radius of the cylinder.
  2. Enter the height of the cylinder.
  3. Read the volume and the surface areas instantly.

Examples

Radius 2, height 5

radius = 2, height = 5
volume = 62.832, lateral area = 62.832, total area = 87.965

Unit cylinder

radius = 1, height = 1
volume = 3.141593, total area = 12.566371

Frequently asked questions

What is the formula for the volume of a cylinder?

The volume equals pi times the radius squared times the height. It is simply the area of the circular base multiplied by the height.

What is the lateral area of a cylinder?

The lateral area is the curved side without the two ends. It equals two times pi times the radius times the height.

How is the total surface area found?

Add the lateral area to the two circular ends. This gives two times pi times the radius times the sum of the radius and the height.

Why are the volume and lateral area equal for radius 2 and height 5?

Both reduce to twenty pi for those numbers. It is a coincidence of the chosen values, not a general rule for cylinders.

What units does this use?

It is unit free. Enter the radius and height in the same unit and the volume is in cubic units and the areas in square units.
