Question 3. ( 10 points) (a) Evaluate the integral f f IEQ: + y + z)e_Z dV, where E lies inside the right circular cylinder of radius 3, and between the planes 2 = 5 and z = 0. (b) Use the spherical coordinates to evaluate the triple integral of the function f(:.~:, y, z) : (a:2 + y2 + z?)_% over the solid E, where E is the solid which lies between the spheres of radii and 3
