2 Let S be the solid of revolution obtained by revolving about the zaxis the bounded region R enclosed by the curve 3.! = e_ 3 and the lines a: = 2, z = 1 and y = [1. We compute the volume of 3 using the disk method. a} Letu be a real number in the interval 2 g a: g 1. The section 2 = 11 ofSis a disI-c. What is the radius and area of the disk? Radius: ' ' n - Area: ' ' n l b] The volume ofS is given by the integral It? f(z)dz where: a. = ' Number ' b = ' Number ' and ri==i=i in c} Find the volume of S with :l:0.1 precision. Volume: ' Number
