To find the volume of the figure.
volume of the figure=volume of the cone+volume of the rectangle prism.
[tex]\begin{gathered} v_1=\frac{\pi r^2h}{3} \\ r=3,h=8 \\ v_1=\frac{3\cdot3\cdot3\cdot8}{3} \\ =72in^3 \end{gathered}[/tex][tex]\begin{gathered} v_2=\text{lwh} \\ l=9,h=9,w=1 \\ v_2=9\cdot9\cdot1 \\ =81in^3 \end{gathered}[/tex]
volume of the figure=72+81=153 inch cube.
