Homework Statement


Find the volume of area the area bounded by x^2+y^2=36, z=x and below the xy plane


Homework Equations





The Attempt at a Solution


I did a triple integral dzdxdy,
where dz is bound between x and 0
dx is bound between 0 and (36-y^2)^(1/2)
and dy is bound between 0 and 6
and got the incorrect answer.
Where did I go wrong here?

You got only half of the correct value, right? Try to draw a diagram of what your bounds correspond to.
Btw, it's not 'dx' etc. that's bound. It's x etc.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
