72 2 -1~ 11: 1. For the integral /// 3; (1V =/ f f y dy d1? dz. do the following. 0 0 u E [8] a] Sketch the region of integration E. and rewrite the integral in the order dz dy (1:17. [8] 1)) Evaluate the integral (using either order). Give your answer an a reduced rational number. [4] (3) Given that the volume of E is 64/5, compute the average value of 3; on E, as a reduced rational number
