The volume of a cylinder is given by:-
[tex]V=\pi\times r^2\times h[/tex]In our question it is given that r=2 and V = 62.8
Now let us calculate the height
[tex]\begin{gathered} 62.8=\pi\times2^2\times h \\ h=\frac{62.8\times7}{4\times22} \\ =\frac{15.7\times7}{22} \\ =4.99 \\ =5\text{ (approx)} \end{gathered}[/tex]So the correct answer is 5m
