How does the Surface Of Revolution Calculator work?

S = 2π ∫ r(t) × √((dx/dt)² + (dy/dt)²) dt (parametric) Then: S = 2π ∫ y × √(1 + (dy/dx)²) dx (Cartesian, rotate around x-axis) Then: r(t) = distance to axis; integrand = arc length element Then: Accounts for both stretching and distance from axis.

Can you give an example of how to use the Surface Of Revolution Calculator?

Example: Input y=x, 0 to 2, x-axis gives a result of SA=4π*sqrt(2).

Is the Surface Of Revolution Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
