Surface Area of a Cone FAQs
How do you calculate the surface area of a cone?
For the total surface area of a cone, add the lateral surface area and the circular base area. Depending on the known values, the calculator can use the radius, diameter, height, and slant height.
What is the difference between total surface area and lateral surface area of a cone?
The lateral surface area includes only the sloped outer surface of the cone. The total surface area also includes the circular base.
Can I calculate the area from the diameter and height?
Yes. If you know the diameter and height, the calculator first finds the radius and slant height and then calculates the requested area.
What is a surface area of a cone calculator useful for?
It is useful for geometry, schoolwork, packaging, funnels, containers, constructions, and other cone-shaped objects.
