## Question:

Evaluate the iterated integral.

{eq}\int_{0}^{3} \int_{0}^{1} \int_{0}^{\sqrt{1 - z^2}} 22ze^y \, \mathrm{d}x \, \mathrm{d}z \, \mathrm{d}y {/eq}

## Iterated Integral

An iterated integral is an integration operation that contains multiple and successive integrals. The function being integrated is usually a multivariate function. To evaluate an iterated integral, start by integrating with respect to the innermost differential while treating all other variables as a constant.
