Learn About Torus Surface Area
A torus, often visualized as a doughnut shape, is a surface of revolution generated by revolving a circle in three-dimensional space about an axis that is coplanar with the circle but does not intersect it. The surface area of a torus measures the total area covering its outer surface.
The formula for the surface area of a torus is given by \(A = 4 \pi^2 R r\), where \(R\) is the major radius (distance from the center of the torus to the center of the tube) and \(r\) is the minor radius (radius of the tube itself). This calculator simplifies the process of finding this area, making it easy for students, engineers, and anyone needing to perform geometric calculations.
