Answer:

no solutions

Step-by-step explanation:

-4(5k-7) +2k= -2(9k+5)

Distribute

-20k +28 +2k = -18k -10

Combine like terms

-18k +28 = -18k -10

Add 18k to each side

-18k+18k +28 = -18k+18k -10

28 = -10

This is never true so there are no solutions

In cylindrical coordinates, the volume is given with

$\displaystyle\int_{\theta=-\pi/2}^{\theta=\pi/2}\int_{r=0}^{r=9}\int_{z=0}^{z=r\cos\theta}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta$
$=\displaystyle\int_{\theta=-\pi/2}^{\theta=\pi/2}\int_{r=0}^{r=9}r^2\cos\theta\,\mathrm dr\,\mathrm d\theta$
$=\displaystyle\left(\int_{\theta=-\pi/2}^{\theta=\pi/2}\cos\theta\,\mathrm d\theta\right)\left(\int_{r=0}^{r=9}r^2\,\mathrm dr\right)$
$=486$
