PMT Leave blank DO NOT WRITE IN THIS AREA WIN Figure 1 2 The curve C with equation y = 4 (4+ 3x) *> - is shown in Figure 1 The region bounded by the curve, the x-axis and the lines x - -1 and x - WIN , is shown shaded in Figure 1 This region is rotated through 360 degrees about the x-axis. (a) Use calculus to find the exact value of the volume of the solid generated. (5) DO NOT WRITE IN THIS AREA Figure 2 Figure 2 shows a candle with axis of symmetry AB where AB = 15 cm. A is a point at the centre of the top surface of the candle and B is a point at the centre of the base of the candle. The candle is geometrically similar to the solid generated in part (a). DO NOT WRITE IN THIS AREA (b) Find the volume of this candle. (2) 8 P 4 6 9 5 8 A 8 4 4
