Hi I am trying to find volume enclosed by following equations: z = 3x, //Top plane x^2 + y^2 = 25, // cylinder x = 4, //line parallel to y axis x, y=0. I am trying to figure out what "Limits" should I take on the "Double Integral" to get the below mentioned Volume ans. Ans. to this problem is "98 cubic units". Thanks for any help!
