**About Disc Volume Calculator (Formula)**

The Disc Volume Calculator is a useful tool for quickly determining the volume of cylindrical discs, commonly used in engineering, manufacturing, and various scientific applications. Understanding the volume of a disc can be essential for material estimation, manufacturing processes, and design specifications. This article will explain the formula for calculating disc volume, provide a step-by-step guide on how to use the calculator, and answer common questions related to disc volume calculations.

### Formula

The formula for calculating the volume of a disc is:

Vdisc = π x (Ro – Ri)² x t

Where:

**Vdisc**is the volume of the disc.**π (pi)**is approximately 3.14159.**Ro**is the outer radius of the disc.**Ri**is the inner radius of the disc.**t**is the thickness of the disc.

### How to Use

**Identify the Radii and Thickness:**Measure or determine the outer radius (Ro), inner radius (Ri), and the thickness (t) of the disc you are interested in.**Input the Values:**Enter these values into the Disc Volume Calculator. Ensure you use consistent units (e.g., all in centimeters or inches).**Perform Calculation:**The calculator will compute the volume based on the provided dimensions.

### Example

Suppose you have the following parameters for a disc:

- Outer radius (Ro) = 5 cm
- Inner radius (Ri) = 2 cm
- Thickness (t) = 3 cm

Using the formula:

Vdisc = π x (5 – 2)² x 3

Vdisc = π x (3)² x 3

Vdisc = π x 9 x 3

Vdisc = 27π

Approximately, Vdisc ≈ 84.82 cm³.

### FAQs

**What is the Disc Volume Calculator?**
