    The internal radius is 11cm

    The external radius is 14cm (answer)

    The hemispherical volume should be

    V = 2/3 x π x (14³ - 11³) = 2959.38028

    {The net space volume between two hemispherical volumes)

    So either you copy the question incorrectly as I cannot read the volume is 942X cm³

    Or the answer is not corresponding to those radii.
