Find the volume of the region that is defined as -1 ≤ y ≤-z-z+2, z 20 and 20 by evaluating the following integral. V= dy dz dz a. First evaluate the innermost integral. Don't forget to substitute the limits! Note that double clicking the integral will show you a zoomed-in version that may be helpful if you are struggling to read the limits. V= = dz dz b. Next, use your answer to part (a) to evaluate the second integral. V= -12.0 dz c. Finally, compute V by evaluating the outermost integral. V= N|R +
