Cylindrical surface area calculator

1. This tool calculates the surface area of a cylinder using its height and radius.

2. Formula: Surface area = 2πrh + 2 * πr²;

(1) π: The mathematical constant pi.

(2) r: The radius of the cylinder.

(3) h: The height of the cylinder.

(4) 2πrh: The lateral surface area of the cylinder.

(5) πr²: The area of the circular cross-section of the cylinder.

3. Note: When entering values, please ensure they are in centimeters (cm); the result is in square meters.

4. Note: The results from this tool are for reference only; for actual applications, please rely on professional equipment.
