Enter the radius and height into the calculator to determine the volume of the Sonotube. This calculator can also evaluate any of the variables given the others are known.

## Sonotube Formula

The following formula is used to calculate the volume of a Sonotube.

V = pi * r^2 * h

Variables:

• V is the volume of the Sonotube
• r is the radius of the Sonotube
• h is the height of the Sonotube
• pi is a mathematical constant whose approximate value is 3.14159

To calculate the volume of a Sonotube, square the radius of the Sonotube, then multiply the result by the height of the Sonotube and the mathematical constant ?.

## What is a Sonotube?

A Sonotube is a brand name for a type of cardboard tube that is commonly used in construction projects. These tubes are typically filled with concrete to create cylindrical columns that can be used as the foundation for structures like decks, lamp posts, and buildings. They are designed to be strong and durable, yet easy to remove once the concrete has hardened. Sonotubes come in a variety of sizes to accommodate different project needs.

## How to Calculate Sonotube?

The following steps outline how to calculate the volume of a Sonotube using the formula V = pi * r^2 * h.

1. First, determine the radius of the Sonotube (r).
2. Next, determine the height of the Sonotube (h).
3. Next, gather the formula from above = V = pi * r^2 * h.
4. Finally, calculate the volume of the Sonotube (V).
5. After inserting the values of r and h into the formula and calculating the result, check your answer with a calculator.

Example Problem:

Use the following variables as an example problem to test your knowledge.

radius of the Sonotube (r) = 5 cm

height of the Sonotube (h) = 10 cm
