Truncated Cone Volume Calculator

With this Omni's truncated cone volume calculator, you will never again have to wonder how to calculate the volume of a truncated cone. Here you'll find the instruction on how to apply the truncated cone volume formula as well as a step-by-step example.

Recall a truncated cone (a.k.a. frustum) is a cone whose top is cut off with a plane parallel to the base. This definition gives us immediately a method of calculating the truncated cone volume: we need to subtract the volume of the smaller cone (the one we cut off) from the volume of the bigger (original) cone. What is left is the volume of the truncated cone. Easy!

Following this line of reasoning and performing some basic math operations, we arrive at the following volume formula for our truncated cone:

V = (1/3) * π * h * (r² + r * R + R²),

Where:

• R is the radius of the base of the original cone (bottom surface);
• r is the radius of the top surface; and
• h is the height of our truncated cone.

To compute the volume of a truncated cone with our tool, you need to:

1. Insert the data you have. Most probably, you know the height h and the top and bottom radii: r and R, respectively.
2. It may happen, in more advanced problems, that you know the slant height s. Insert whatever you have!
3. The Omni magic happens, and the empty fields, including volume, fill in immediately.
4. Adjust the units if needed.

As you can see, Omni's truncated cone volume calculator is a very straightforward tool!

36.65 cm³. To get this result you need to remember the truncated cone volume formula: V = (1/3) * π * h * (r² + r * R + R²). Plugging in h = 5, r = 1, and R = 2, we arrive at the desired result.

To calculate the volume of a truncated cone, follow these steps:

1. Determine the top and bottom radii of your frustum: r and R, respectively.
2. We will also need the height h of the solid (the perpendicular distance between the two parallel surfaces).
3. Now, apply the formula: V = (1/3) * π * h * (r² + r * R + R²), where π ≈ 3.14.
4. That's it! You've just determined the volume of your frustum.
