A right circular cone sits on a table, pointing upwards. The cross-section triangle, perpendicular to the base, has a vertex angle of 45 degrees. The diameter of the cone's base is $16$ inches. A cylinder is also placed co-axially inside the cone, its height equal to the height of the cone and its diameter equal to half of the cone's base diameter. A sphere is placed inside the cylinder so that it is tangent to the sides of the cylinder and to the cone's sides. What is the volume, in cubic inches, of the sphere? Express your answer in terms of $\pi$.
