Surface Area of a Cone Calculator - Instant Geometry Tool

Calculate Cone Surface Area

Unravel the complexities of cone geometry with our free Surface Area of a Cone Calculator. Whether you're a student, engineer, or designer, this tool helps you instantly determine both the total and lateral surface area of any cone. Simply input the radius and height to get accurate results for your projects and studies.

Formula:

The total surface area (SA) of a cone is found by adding the area of its circular base to its lateral surface area. The formula is:

SA = πr2 + πrL

Where the slant height (L) is calculated as: L = √(r2 + h2)

  • r = Radius of the cone's base
  • h = Perpendicular height of the cone
  • L = Slant height of the cone
  • π ≈ 3.14159 (mathematical constant Pi)
