Torus Surface Area Calculator
Calculate the surface area of a torus using our online calculator. Perfect for geometry enthusiasts and students.
What is the Torus Surface Area Calculator & How does it work?
A torus is a three-dimensional shape formed by revolving a circle in a plane around an axis that lies in the same plane but does not intersect the circle. The surface area of a torus can be calculated using the formula:This formula arises because the surface area of a torus is the product of the circumferences of two circles: one with radius R and another with radius r.
A = 4pi^2 Rr
R = major radius (distance from the center of the tube to the center of the torus)
r = minor radius (radius of the tube)
r = minor radius (radius of the tube)

Frequently Asked Questions
How do I calculate the surface area of a torus?
Use the formula A = 4π² Rr, where R is the major radius and r is the minor radius.
What are the major and minor radii in a torus?
The major radius (R) is the distance from the center of the tube to the center of the torus. The minor radius (r) is the radius of the tube itself.
Can I use this calculator for any shape?
No, this calculator is specifically for calculating the surface area of a torus.
What units should I use for R and r?
Use consistent units for both R and r. If you input them in meters, the result will be in square meters.
Is there a maximum value for R or r?
There is no strict limit, but very large values may lead to computational errors depending on your device.
How accurate is this calculator?
This calculator provides precise results based on the formula A = 4π² Rr.
Can I use this calculator for educational purposes?
Yes, it's a useful tool for students and educators to understand torus geometry.
