Let S to the solid of revolution obtained by revolving about the s-axis the bounded region Renclosed by the curve y = -28 and the ne-1 = 2 and y = 0. We compute the volume of using the disk method a) Let u be a real number in the interval -1 <12. The section r = u of Sis a disk. What is the radius and area of the disk? Radius: Area: ) b) The volume of S is given by the integral e f (x)da, where: a = 1
b = -2 and f() = Plo c) Find the volume of S with +0.01 precision Volume: 42.888
