About this calculator
A cone is a cylinder with one end pinched to a point. Volume = (1/3) × base area × height = (1/3)πr²h — exactly one-third of the corresponding cylinder. Slant height = √(r² + h²) is the distance from apex to base edge. Lateral surface = πr × slant. Used in ice cream cones, party hats, traffic cones, and conical roofs.
