Correct. The shape is a cone. The formula for its volume is $\displaystyle{V}=\frac{{1}}{{3}}\pi{{r}}^{{2}}{h}\usepackage{cmbright}\Huge\$ . Substitute $\displaystyle{r}={3}\usepackage{cmbright}\Huge\$ and $\displaystyle{h}={8}\usepackage{cmbright}\Huge\$ into the formula:

$\displaystyle{V}=\frac{{1}}{{3}}\pi{{\left({3}\right)}}^{{2}}{\left({8}\right)}=\frac{{1}}{{3}}\pi{\left({9}\right)}{\left({8}\right)}=\frac{{1}}{{3}}\pi{\left({72}\right)}\approx\frac{{1}}{{3}}\cdot{3.14}\cdot{72}\approx{75.4}\usepackage{cmbright}\Huge\$
