Volume of solid sphere with radius 4 cm is, = $$frac{4}{3} pi (4)^{3} cm^{3}$$ Volume of hollow sphere with outer diameter 16 (r = 8) and inner diameter 12 (r = 6) is, = $$frac{4}{3} pi (8^{3} - 6^{3}) cm^{3}$$
= $$frac{4(512 - 216)}{4^{3}}$$ = $$frac{296}{4^{2}}$$ = $$18.5$$
Hence, option D is the correct answer.
