In this question, we have to use the formula of volume of sphere, which is

$V= (4)/(3) \pi r^3$

S for gumball, volume is

$= (4)/(3)* \pi (27)^3 = 82447.96 mm^3$

Volume of the gumball's spherical hollow core is

$= (4)/(3)* \pi*23^3=50965.01mm^3$

Required volume is the difference of the volume of gumball and gumball's spherical hollow core, that is

V=82447.96-50965.01= 31482.95 mm^3
