Cone class

A class representing a cone in 3D space.

A cone is a solid that has a circular base and a single vertex. This implementation assumes a right circular cone.

Properties:

  • Radius (of the base)
  • Height
  • Slant Height = √(r² + h²)
  • Volume = (1/3) × π × r² × h
  • Surface Area = πr(r + s)

Example:

var cone = Cone(radius: 3.0, height: 4.0);
print('Slant Height: ${cone.slantHeight}'); // 5.0
print('Volume: ${cone.volume()}');
