Cone surface area calculator

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

2. Formula: Surface area of a cone = πr² + πrh;

(1) π: The mathematical constant pi.

(2) r: The radius of the circle at the base of the cone.

(3) h: The height of the cone.

3. Note: Please ensure that values are entered in centimeters (cm); results are displayed in square meters.
