Instantly calculate the surface area of a torus, also known as a donut shape, with our intuitive online tool. Understand the impact of major radius and minor radius on this complex 3D geometric figure. Ideal for students, engineers, and designers working with toroidal shapes. Get precise results for your calculations effortlessly.
Formula:
The surface area of a torus (A) is calculated using the formula:
A = 4π²Rr
Where:
- R = Major Radius (distance from the center of the hole to the center of the tube)
- r = Minor Radius (radius of the tube's cross-section)
- π ≈ 3.14159
