Part 1 of 5 When y = 4 - 4x2 is rotated around the x-axis, a vertical strip of width Ax creates a disk. The radius of this disk is r = 4 - 4x- 4-472 y = 4-4x2 o y=0 Part 2 of 5 The cross-sectional area of a disk of radius r is A = nr Since our disk has radius r = 4 - 4x2, then the cross-sectional area is A = 1(4 -4x2)2 = (4-47)? Part 3 of 5 K The function y = 4 - 4x intersects the x-axis at the following values of x. (smaller value) * = (larger value)
