Solution

I : height = 28 & radius = 28/2 = 14

Since, both radius and height are known, we can find the volume of cylindrical tank = $\pi$ * $R^{2}$ * h$

= $\frac{22}{7} * 14*14*28 = 17248$ CU m.

Thus, I alone is sufficient.

II : height = 28

area of base = $\pi$ * $r^{2} = 616$

Volume = area of base * height $= 616*28 = 17248 m^{3}$

Thus, II alone is also sufficient.
