Volume usingiterated triple integral

Click For Summary
SUMMARY

The discussion focuses on setting up an iterated triple integral to calculate the volume of a region in the first octant, enclosed by the cylinder defined by the equation x² + y² = 4 and the plane z = 4. The correct limits for the integral are x from 0 to 2, y from 0 to √(4 - x²), and z from 0 to 4. A critical correction was made regarding the limits for y, as using -√(4 - x²) does not conform to the first octant constraints.

PREREQUISITES
  • Understanding of triple integrals in calculus
  • Familiarity with cylindrical coordinates
  • Knowledge of the first octant in three-dimensional space
  • Ability to interpret geometric constraints from equations
NEXT STEPS
  • Study the application of cylindrical coordinates in triple integrals
  • Learn how to visualize regions defined by inequalities in three dimensions
  • Practice setting up iterated integrals for various geometric shapes
  • Explore the concept of volume calculations using multiple integrals
USEFUL FOR

Students studying calculus, particularly those focusing on multivariable calculus and triple integrals, as well as educators looking for examples of volume calculations in three-dimensional geometry.

Homework Statement



Write an iterated triple integral in the order dzdydx for the volume of the region in the first octant enclosed by the cylinder x2+y2=4 anf the plane z=4. (You do not need to evaluate)

Homework Equations





The Attempt at a Solution


I think I have the right set up, but I wanted to make sure. V=∭ dzdydx ... x from 0 to 2, y from -sqrt(4-x2) to sqrt(4-x2) and z from 0 to 4...

Thanks for the help in advance

-sqrt(4-x2) isn't the first octant.
