Best ResponseYou've already chosen the best response.0if the radius of the littest sphere is r=4 cm, and the radius of the bigger sphere is R=5 cm, then the requested volume V is: \[\Large V = \frac{{4\pi }}{3}{R^3}  \frac{{4\pi }}{3}{r^3} = \frac{{4\pi }}{3}{5^3}  \frac{{4\pi }}{3}{4^3} = ...c{m^3}\]

Best ResponseYou've already chosen the best response.0it asks 'approximately' so you could approximate pi to 3 so volume ~= 4(5^34^3)
