(A) The radius of a nucleus is given by the relation $R = R_0 A^{1/3}$,where $R_0 \approx 1.2 	imes 10^{-15} 	ext{ m}$ and $A$ is the mass number.The volume $V$ of a nucleus is given by the formula for the volume of a sphere:$V = \frac{4}{3} \pi R^3$Substituting the expression for $R$:$V = \frac{4}{3} \pi (R_0 A^{1/3})^3$$V = \frac{4}{3} \pi R_0^3 A$Since $\frac{4}{3} \pi R_0^3$ is a constant,the volume $V$ is directly proportional to the mass number $A$ $(V \propto A)$.
