CALCULATOR
Right Circular Cylinder Lateral Area Calculator
Find curved cylinder surface without ends. Example: Radius: 2 m, Perpendicular height: 2 m gives 25.1327412287 m². Right circular cylinder; height is perpendicular to its circular bases. Both circular end faces excluded. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation.
Right circular cylinder; height is perpendicular to its circular bases. Both circular end faces excluded. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Unroll circumference 2πr times height h.
Accepted inputs: Radius: 0.001 to 1,000 m; Perpendicular height: 0.001 to 1,000 m.
How the calculation works
A_lateral = 2πrh
Worked example
With radius 2 m, perpendicular height 2 m, curved cylinder surface without ends is 25.13274123 m².
Assumptions and limits
Right circular cylinder; height is perpendicular to its circular bases. Both circular end faces excluded. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Unroll circumference 2πr times height h.
