Lateral surface area of elliptic cylinder (LSA) is the side surface of the cylinder leaving the base and top. Here it refers to the total vertical area of the cylinder that lies between elliptical base and top. Use our online lateral surface area of elliptical cylinder calculator to find the LSA based on semi-major and semi-minor axis along with height. As there was no closed form for the circumference of an ellipse, it is found using an approximation formula.

Lateral Surface Area = h × 2 × π × √((1/2) × ((A × A) + (B × B)))

Calculate lateral surface area of elliptic cylinder having a height of 7 cm, semi-major and semi-minor axis of 5 cm and 4 cm.

LSA = 7 × 2 × π × √((1/2) × ((5 × 5) + (4 × 4)))

= 199.1383 cm^{2}
