Calculus Using Integrals to Find Areas and Volumes Calculating Volume using Integrals 1 Answer Morgan Nov 22, 2016 Graph the solid, determine the limits of integration, then integrate. @inquisitor Yes. Choose Z for the integrated. What does "Welcome to SeaWorld, kid!" So E = { $(x,y,z) | 0 \leq x \leq 4, 0 \leq y \leq \sqrt{4 - x}, 0 \leq z \leq 2-y$} and the projected xy plane would be the function $y = \sqrt{4 - x}$. Log in here. Why is it "Gaudeamus igitur, *iuvenes dum* sumus!" I know that y and x are bounded by $0$ on the left because it is the first octant. The two planes can be drawn easily if you user the x, y and z intercepts. We now determine the limits of integration by examining a cross section in the #xy#-plane which is a quarter circle of radius 3 centred at the #O#, and so we have: # 0 le x le sqrt(9-y^2)# and # 0 le y le 3#, # v= int_0^3 int_0^(sqrt(9-y^2)) (9-x) \ dx \ dy #. The question is: Find the volume of the solid in the first octant bounded by $x+y+z=1$ and $x+y+2z=1$.
