Incorrect. A soup can is shaped like a cylinder, so use the formula $\displaystyle{V}=\pi{{r}}^{{2}}{h}\usepackage{cmbright}\Huge\$ . Can A has $\displaystyle{d}={8}\usepackage{cmbright}\Huge\$ , so $\displaystyle{r}={4}\usepackage{cmbright}\Huge\$ , and $\displaystyle{h}={15}\usepackage{cmbright}\Huge\$ . Can B has $\displaystyle{d}={10}\usepackage{cmbright}\Huge\$ , so $\displaystyle{r}={5}\usepackage{cmbright}\Huge\$ , and $\displaystyle{h}={12}\usepackage{cmbright}\Huge\$ . Substitute these values into the formula and calculate the volume of each can. Then subtract the volume of Can A from the volume of Can B.
