Incorrect. The formula for the volume of a cylinder is $\displaystyle{V}=\pi{{r}}^{{2}}{h}\usepackage{cmbright}\Huge\$ and the formula for the volume of a cone is $\displaystyle{V}=\frac{{1}}{{3}}\pi{{r}}^{{2}}{h}\usepackage{cmbright}\Huge\$ . For both parts, $\displaystyle{r}={4}\usepackage{cmbright}\Huge\$ . For the cylinder, $\displaystyle{h}={7}\usepackage{cmbright}\Huge\$ . For the cone, $\displaystyle{h}={6}\usepackage{cmbright}\Huge\$ . Substitute these numbers into the formulas and simplify. Then, add the volumes of the two solids together to find the total volume.
