Can I calculate the surface area of a sphere if I only know its diameter?

The calculator supports multiple output units. Select your preferred unit from the dropdown menu after entering your dimensions to view the result in that unit.

Does the calculator show the formula used for each shape?

The page displays the surface area result but does not list the underlying formula for each shape; users familiar with geometry will recognize the standard formulas for spheres, cones, cylinders, and cubes.

Is there a limit to the number of shapes I can calculate in one session?

No session limit is mentioned; users can calculate surface areas for multiple shapes sequentially by switching between the different shape calculators on the page.
