How do I calculate the surface area of a cone if I only have the radius and slant height?

Enter the radius and slant height values into the calculator; it will compute the total surface area by adding the base area and the lateral surface area.

Can I use this tool if I have the radius and vertical height instead of the slant height?

Yes, the calculator accepts the radius and vertical height; it will determine the slant height internally to compute the surface area.

What units are supported for the input and output?

The tool supports various length units for inputs and provides the surface area in square units matching the selected measurement unit.

Is the calculator accurate for oblique cones or only right circular cones?

This tool is designed for right circular cones; using it for oblique cones may produce inaccurate results as the formula assumes a specific geometric shape.
