Can someone help with this question:

2 2 2 Find the volume of the solid bounded above by the surface z = : y2 + 6 and below by the surface z = z + y + 4. Enterthe exact value of the volume in Maple syntax in the box below. 4D Hint: Use polar coordinates. Suppose that the lamina is the region bounded by the curves 1; = 22 , .1: = 1 and the z-axis as shown below. 1 0.8 0.6 0.4 0.2 The variable densityr of the lamina is given by ay} = 9523 3.3. (a) Enter the exact value of the Mass of the lamina in the boxes below. Mass: .D (b) Enter the exact value of the moment of inertia ofthe lamina about the gals in the box below. 1y: .El
