Chapter 14.5, Problem 25ES

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

$\begin{array}{l}\left(\text{a}\right){\displaystyle {\int }_{-1}^1{\displaystyle {\int }_{-\sqrt{1-x^2}}^{\sqrt{1-x^2}}{\displaystyle {\int }_0^{y+1}dzdydx}}}\\ \left(\text{b}\right){\displaystyle {\int }_0^9{\displaystyle {\int }_0^{y/3}{\displaystyle {\int }_0^{\sqrt{y^2-9x^2}}dzdxdy}}}\\ \left(\text{c}\right){\displaystyle {\int }_0^1{\displaystyle {\int }_0^{\sqrt{1-x^2}}{\displaystyle {\int }_0^{2}dydzdx}}}\end{array}$
