Ring volume formula:
   V = π2 * (R + r) * (R - r)2

Ring area formula:
   S = π2 * (R2 - r2)

   R: outer radius
   r: inner radius

A Ring Volume and Surface Area Calculator is a tool designed to help you calculate the volume and surface area of a ring-like shape (such as a torus). A ring, in this case, can be thought of as a three-dimensional object with a hollow center and a tube-like shape, like the shape of a donut.

Why Use It?

This calculator is useful for solving real-world problems involving ring shapes in fields like engineering, physics, architecture, and design. For example, it can be used to determine the amount of material needed to construct a ring-shaped object or to calculate the flow of fluids around a ring.

When to Use It:

  • When designing ring-shaped objects, such as wheels, pipes, or any object that has a hollow circular shape.
  • In fluid dynamics, when studying the flow around a torus or in a ring-shaped pipe.
  • In engineering, to calculate materials for manufacturing ring-shaped components.
