3) In the following problems, find the volume when the region is rotated around the indicated axis. a. The region bounded by y = sin x, y = cos x, and x = 0 ; rotated around the x- axis b. The region bounded by y = Vx and y = x ; rotated around the y-axis; use the washer method 4) In the following problem, use shells to find the volumes of the given solids. 1 a. The region bounded by y = V14x2 , * = 0,x = = , y = 0 ; and is rotated around the y-axis x3 b. The region bounded by y = 2 , x = 0, x = 2, and y = 0; and is rotated around the x-axis
