d. It is proposed that the casting table be changed to produce billets of the same radius but with a flat side to allow improved stacking and handling. One of the negative impacts of this will be a reduction of mass for the proposed billet compared with the original. The figure below shows a sketch of a cross-section through the proposed new billet shape, a circle with a flat cast onto one side. The shaded area represents the new aluminium billet, determine: iii. The height perpendicular to the flat, h The area of the shaded portion The area of the unshaded area (and hence the proportional difference in mass between the proposed billet and the existing design) 12 cm 66 12 cm h d.
