Measure the height (h) of the cylinder. Height is sometimes referred to as the length.
How to Calculate the Volume of a Cylinder
Found This Helpful
A cylinder is a threedimensional solid with 2 bases, 2 edges and 3 faces. You measure the volume of a cylinder in cubic units of measurement. You can calculate the volume of a cylinder using these short and simple steps.

2
Measure the radius (r) of the cylinder. Radius is the distance from the outer edge to the center of the circle.

3
Multiply the height by Pi.

4
Square the radius. (Multiply the radius by itself.)

5
Multiply the product from Step 3 by the product of Step 4.

6
Write you answer in the proper cubic unit of measurement.

Tips & Warnings
 Make sure you use the same unit of measurement for each dimension.
 For a complicated shape, break it down into smaller parts. Determine the volume of smaller parts, and then combine them (by adding) to find the volume of the entire shape.
