ANSWER:Solution 34E: Here, we have to calculate the volume of the cylinder which is called boules We know Volume of a silicon boule is = r h 2 Where, r is the radius of the cylinder and h is the height of the cylinder Given in the question Diameter of the silicon boule = 300 mm Radius of the silicon boule (r) = 300mm/2 = 150 mm Now we have to convert mm to m -3 1 mm = 10 m 150 mm = 150 x 10 m -3 = 0.15 m Thus radius of the silicon boule is (r)= 0.15 m height of the silicon boule (h) = 2 m 2 22 2 Thus, Volume of a cylinder is = r h = 7 x (0.15 m) x 2 m 3 = 0.99/7 m Volume of the silicon boule = 0.1413 m 3 -3 3 = 141.3 x 10 m Now we have to calculate the volume of the silicon wafer Diameter of the silicon wafer = 300 mm Radius of t
