Sobre esta calculadora

The Sphere & Solid Geometry Calculator finds the volume and surface area of a sphere, cone, or cylinder from its radius and height. It also reports the slant height, lateral and base areas, great-circle area, and diameter, with an explanatory cross-section diagram. Useful for geometry homework, engineering, and 3D design.
