Volume of a Solid using Triple Integrals

Click For Summary
The discussion focuses on using a triple integral to calculate the volume of a solid defined by the cylinder z=y² and the planes x=0, x=6, and z=16. The integral was set up in rectangular coordinates with the region defined as D = { (x,y,z) | 0 < x < 6, -4 < y < 4, y² < z < 16 }. The participant calculated the volume to be 512 and sought confirmation of their solution. Feedback from others indicated that the limits of integration were correct, and as long as there were no arithmetic errors, the answer should be valid. The discussion emphasizes the importance of verifying calculations in multivariable calculus.

Homework Statement



Use a triple integral to find the volume of the solid enclosed by the cylinder z=y2 and the planes x=0, x=6, and z=16. Set up the integral in rectangular coordinates and work it out in any coordinates.

The Attempt at a Solution



I set up the triple integral using these orders of integration:

D = { (x,y,z) | 0 < x < 6, -4 < y < 4, y2 < z < 16 }

And I obtained an answer of 512. I just wanted to make sure that I did all the work correctly, and that someone more experienced could say if it is correct.
Thank you!

Your limits look good so if you didn't make any arithmetic mistakes it should be correct.

Thank you very much, Mr Kurtz!
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
