Chapter 14.5, Problem 26ES

In each part, sketch the solid whose volume is given by the integral.

$\begin{array}{l}\left(\text{a}\right){\displaystyle {\int }_0^3{\displaystyle {\int }_{x^2}^9{\displaystyle {\int }_0^{2}dzdydx}}}\\ \left(\text{b}\right){\displaystyle {\int }_0^2{\displaystyle {\int }_0^{2-y}{\displaystyle {\int }_0^{2-x-y}dzdxdy}}}\\ \left(\text{c}\right){\displaystyle {\int }_{-2}^2{\displaystyle {\int }_0^{4-y^2}{\displaystyle {\int }_0^{2}dxdzdy}}}\end{array}$
