The incenter of △ABC\triangle A B C△ABC is denoted as III. Given that AI=12 cmA I=12 \mathrm{~cm}AI=12 cm and BE=8 cmB E=8 \mathrm{~cm}BE=8 cm, find the length of DED EDE.A cylindrical vessel of base radius 42 cm contains water to a certain level. A solid cylinder of height 18 cm is dropped into it and is completely submerged in water. If the level of the water in the vessel rises by 6 cm, what is the total surface area (in cm²) of the solid cylinder? (Use π=227\pi = \frac{22}{7}π=722 ) (Assuming no overflow.)
