# How to Calculate the Volume of a Cylinder

Save

A cylinder is a three-dimensional 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.

### Things You'll Need

• Cylinder
• Formula for volume of a cylinder, V =(Pi)(h)(r)(r)
• Calculator (if needed)
• Measure the height (h) of the cylinder. Height is sometimes referred to as the length.

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

• Multiply the height by Pi.

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

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

• 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.
