The total $($absolute$)$ pressure at the bottom of a cylindrical container that is open to an atmosphere and has a

cross$-$sectional area of $58$ cm$2$

and holding some amount of gasoline is $115$ kPa.

$($a$)$ Determine the depth of the gasoline.

$($b$)$ Determine the pressure at the bottom of the container if an additional $2\mathrm{.}8$ x $10-3$ m$3$

of gasoline is added

to the container.
