Volume:-

$\\ \sf\rightarrowtail (4)/(3)\pi r^3$

$\\ \sf\rightarrowtail (4)/(3)\pi (0.18)^3$

$\\ \sf\rightarrowtail (4)/(3)\pi (0.005832)$

$\\ \sf\rightarrowtail 0.024m^3$

Density:-

$\\ \sf\rightarrowtail (Mass)/(Volume)$

$\\ \sf\rightarrowtail (190)/(0.024)$

$\\ \sf\rightarrowtail 7916.67kg/m^3$
