    Answer:

    Internal Diameter = 6cm

    External   Diameter = 10 cm

    Internal radius = 3cm

    External radius = 5 cm

    So the Volume  of hemisphere

    = (2/3)π(5³ – 3³) cm³

    = 196π/3 cm³

    = 196π/3 cm³Volume of solid cylinder = πr²h cm³

    Diameter = 14 cm

    So radius = 7 cm

    Let  h = height of the cylinder

    So by the given condition

    π(7)²h  = 49πh

    49πh  = 196π/3

    49πh  = 196π/3h = 4/3

    So the required height is 4/3 cm
