Part 1: Part 3: Use the method of cylindrical shells to find Let S be the solid obtained by rotating the the volume V generated by rotating the region shown in the figure about the y- region bounded by the given curves axis. (Assume a = 4 and b = 2.) about x =: 2. y = 10x4, Y = 0, X - 1 y = asn(bx) Rotating a vertical strip around x = 2 creates a cylinder with radius / = ? And heighth=? V = ? Part 2: Find its circumference c and height h. Compute the exact length of the curve c(x) ? h(x)-? . V=? f (X ) = V 25t - 1 Part 4: dt 1 Let S be the solid obtained by rotating the over the interval region shown in the figure about the y- [2.5]. axis. (Assume a = 4 and b = 2.) First, set up the integral, then solve the exact length. max ( x - by h(x)=
