Expressing volume of bounded solid as iterated integral(s)

168 Views Asked by At

I want to express $\iiint_E f(x,y,z) \ dV$ as an iterated integral.

The solid is bounded by the surfaces $y^2+z^2=9$, $x=-2$, $x=2$.

Looking at the projection on the plane x=0, the trace is a circle with radius 3 and center $(y,z)=(0,0)$. So $[(y,z)|-3\leq y\leq 3, -\sqrt{9-y^2} \leq z \leq \sqrt{9-y^2}]$

This would give the iterated integral:

$$\int_{-3}^{3}\int_{-\sqrt{9-y^2}}^{\sqrt{9-y^2}}\int_{-2}^{2} \ dx\ dz\ dy$$

In a similar way, I came up with the following variations of the integral:

$$\int_{-3}^{3}\int_{-\sqrt{9-z^2}}^{\sqrt{9-z^2}}\int_{-2}^{2} \ dx\ dy\ dz$$

$$\int_{-3}^{3}\int_{-2}^{2}\int_{-\sqrt{9-z^2}}^{\sqrt{9-z^2}} \ dy\ dx\ dz$$

$$\int_{-2}^{2}\int_{-3}^{3}\int_{-\sqrt{9-z^2}}^{\sqrt{9-z^2}} \ dy\ dz\ dx$$

$$\int_{-3}^{3}\int_{-2}^{2}\int_{-\sqrt{9-y^2}}^{\sqrt{9-y^2}} \ dz\ dx\ dy$$

$$\int_{-2}^{2}\int_{-3}^{3}\int_{-\sqrt{9-y^2}}^{\sqrt{9-y^2}} \ dz\ dy\ dx$$

Have I created the bounds on the integrals correctly, and are these all the ways to form the iterated integral?
