Cylinders can be found as cakes, posts, rebar, tanks, pipes, wire, hoses, dowels, pins, axles, drive shafts, washers in structures, hinges, vehicles, tools, drive systems. An oblique cylinder can be found on the job every time a pipe or round dowel is cross cut on an angle.**VOLUME OF A Cylinder**

**Formula for the volume of a cylinder**

**Example:**

Calculate the volume of a cylinder that has a diameter of 20 cm and a height of 50 cm.

The volume of the cylinder is 15,708 cm^{3}

In your trades books the word “altitude” (A) may be used instead of height (H).

The formula then may look like this:

^{2}A or

The problem with altitude (A) is that the word “area” is also abbreviated as (A)

To avoid confusion, the word altitude is not used on this site, only in aviation context.

Check out the ADVANCED tab. The exercises will further your understanding and help with building a bigger mental picture. It builds links between numbers and algebra. It is important to sketch the shapes, label the shapes with the given numbers, tracking changes to units of measure, visualizing to cross-link the concepts of volume and numbers. We use the numbers from this concrete cylinder example.
