Answer 1

To find the volume of the figure.

volume of the figure=volume of the cone+volume of the rectangle prism.

`\begin{gathered} v_1=(\pi r^2h)/(3) \\ r=3,h=8 \\ v_1=(3\cdot3\cdot3\cdot8)/(3) \\ =72in^3 \end{gathered}`
`\begin{gathered} v_2=\text{lwh} \\ l=9,h=9,w=1 \\ v_2=9\cdot9\cdot1 \\ =81in^3 \end{gathered}`

volume of the figure=72+81=153 inch cube.
