Answer: Option A
Let the radius of the cylinder be r and height be h
Then, r + h = 19
Again, total surface area of cylinder = $$\left( {2\pi rh + 2\pi {r^2}} \right)$$
Now,
$$\eqalign{
& 2\pi r\left( {h + r} \right) = 1672 \cr
& \Rightarrow 2\pi r \times 19 = 1672 \cr
& \Rightarrow 38\pi r = 1672 \cr
& \therefore \pi r = \frac{{1672}}{{38}} = 44\,m \cr
& \therefore r = \frac{{44 \times 7}}{{22}} = 14\,m \cr} $$
∴ Height = 19 - 14 = 5 m
Volume of cylinder :
$$\eqalign{
& = \pi {r^2}h \cr
& = \frac{{22}}{7} \times 14 \times 14 \times 5 \cr
& = 22 \times 2 \times 14 \times 5 \cr
& = 3080\,{m^3} \cr} $$
