      (I) Radius of cone r = 6 cm and height h = 7 cm
      Volume of cone = 1/3πr²h
      = 1/3 × 22/7 × 6 × 6 × 7 = 264 cm³
      Hence, the volume of right circular cone is 264 cm³.
      (II) Radius of cone r = 3.5 cm and height h = 12 cm
      Volume of cone = 1/3πr²h
      = 1/3 × 22/7 × 3.5 × 3.5 × 12 = 154 cm³
      Hence, the volume of right circular cone is 154 cm³.
