Find the volume of the cylinder and sphere Part A and B

Given data:
The volume of the cone is V= 48 cubic units.
The expression for the volume of cone is,
[tex]\begin{gathered} V=\frac{1}{3}\pi(r)^2h \\ 48=\frac{1}{3}\pi(r)^2h \\ 144\text{ =}\pi(r)^2h \end{gathered}[/tex]Here, π(r)^2 h is nothing just the volume of cylinder.
[tex]144cubic-units=V_c[/tex]Thus, option (D) is correct.
