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