Area Calculator FAQ
How do you calculate the surface area of a torus?
To calculate the surface area of a torus, this calculator uses the major and minor radii or the major and minor diameters and finds the full outer surface of the torus.
Can I calculate the surface area of a torus from the diameters?
Yes. If you know the major and minor diameters, the calculator first finds the matching radii and then calculates the torus surface area.
What is the difference between the major and minor radius of a torus?
The major radius is the distance from the center of the torus to the center of the tube, while the minor radius is the radius of the tube itself. Together they define the shape and size of the torus.
What is a torus surface area calculator useful for?
It is useful for geometry, homework, models, technical estimates, and any situation where you need the outer surface area of torus, ring-shaped, or donut-like objects.
