Answer: 1539π cubic inches.

Explanation:

In the figure, we have a hemisphere joined with a cylinder of the same diameter 18 inches.

Radius = 9 inches (half of diamter)

Volume of hemisphere =
$\frac23 \pi r^3$

Volume of cylinder =
$\pi r^2 h$ , where r= radius h= height

Volume of hemisphere=
$(2)/(3)\pi (9)^3=486\pi in.^3$

Volume of cylinder =
$\pi (9)^2 (13)=1053\pi\ in.^3$

Combined volume = 486π+1053π=1539π cubic inches.

Hence, the volume of the solid = 1539π cubic inches.
