Work Step by Step
In the xy plane $(z=0)$:
$\displaystyle \frac{x^{2}}{3^{2}}+\frac{y^{2}}{2^{2}}=1\qquad$ ... ellipse
In the xz plane ($y=0)$
$\displaystyle \frac{x^{2}}{3^{2}}+\frac{z^{2}}{3^{2}}=1\qquad$ ... circle
In the yz plane $(x=0):$
$\displaystyle \frac{y^{2}}{3^{2}}+\frac{z^{2}}{2^{2}}=1\qquad$ ... ellipse
