$2-6$ A cylindrical tank filled with a fluid has a diameter of $1$ m

$($M$)$ and a length of $1\mathrm{.}5$ m $.$ It weighs $6000$ N $,$ where the gravita$-$

tional acceleration is $9\mathrm{.}82\frac{m}{s^2}.$ Determine:

$($a$)$ Volume occupied by the fluid

$($b$)$ Specific weight of the fluid

$($c$)$ Density of the fluid

$($d$)$ Specific gravity of the fluid
