The adjoining figure shows the cross–section of an ice–cream cone consisting of a cone surmounted
by a hemisphere. The radius of the hemisphere is 3.5 cm and the height of the cone is 10.5 cm.
The outer shell ABCDEF is shaded and is not filled with ice cream. AE = DC = 0.5 cm, AB || EF
and BC || FD. Calculate
(i) The volume of the ice-cream in the cone (the unshaded portion including
