A donut shop is developing a new product, the hexagonal donut, as shown in Fig.3(a). It is a circular donut with a hexagon cross-section, equivalent to rotating a hexagon about the vertical axis, as shown in Fig. 3(b). To estimate the amount of icing sugar needed for each donut, please determine (a) its surface area. Also, to estimate flour usage for each donut, please determine (b) its volume. | 40 mm | | | | (a) (b) Fig. 3 60° 60° 60% 20 mm
