Cone Lateral Surface Area حاسبة

Calculates the lateral surface area of a cone (side surface, excluding base).

Measure or calculate the base radius Then: Determine slant height (or calculate from height) Then: Apply the lateral area formula Then: Add base area if total surface area needed.

Example: Input Radius: 5 cm, Slant Height: 13 cm gives a result of Lateral Area ≈ 204.2 cm² (Different from total surface area which includes base).
