The Surface Area of a Cone calculator computes the surface area as a function of the radius of the base (r) and the height (h).  Right circular cone 

INSTRUCTIONS: Choose the preferred units and enter the following:

• (h)  This is the height of the cone
• (r)   This is the radius of the based of the cone.

Cone Surface Area:  The surface area (A) is returned in square meters (m²).  However, this can be automatically converted to other area units via the pull-down menu.

Cone Calculators: 

1. Surface Area:  cone surface area based on cone height and cone base radius
2. Volume: cone volume based on cone height and cone base radius
3. Mass: cone mass or weight as a function of the volume and mean density
4. Frustum Surface Area: cone frustum surface area based on the two heights and two radii
5. Frustum Volume: cone frustum volume based on the two heights and two radii 
6. Frustum Mass: cone frustum weight or mass based on the cone frustum volume and mean density
7. Shell Volume: cone shell volume a.k.a. hollow cone volume
8. Shell Mass: cone shell mass or weight a.k.a. hollow cone mass.

General Information

Height is defined as the length of the central axis from the base to the apex of the cone. See diagram.
