Closed Right Circular Cylinder Surface Area Calculator
Find curved surface and both end faces. Example: Radius: 2 m, Perpendicular height: 2 m gives 50.2654824574 m². Right circular cylinder; height is perpendicular to its circular bases. Closed circular cylinder with two end faces. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calcula
Right circular cylinder; height is perpendicular to its circular bases. Closed circular cylinder with two end faces. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Two circles 2πr² plus unrolled rectangle 2πrh.
Accepted inputs: Radius: 0.001 to 1,000 m; Perpendicular height: 0.001 to 1,000 m.
How the calculation works
A = 2πr(r+h)
Worked example
With radius 2 m, perpendicular height 2 m, curved surface and both end faces is 50.26548246 m².
Assumptions and limits
Right circular cylinder; height is perpendicular to its circular bases. Closed circular cylinder with two end faces. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Two circles 2πr² plus unrolled rectangle 2πrh.
