Answer & Solution
Correct Answer:
Option
D
Volume :
$$\eqalign{ & = \pi {r^2}h \cr & = \left( {\frac{{22}}{7} \times 1 \times 1 \times 14} \right){m^3} \cr & = 44\,{m^3} \cr} $$
$$\eqalign{ & = \pi {r^2}h \cr & = \left( {\frac{{22}}{7} \times 1 \times 1 \times 14} \right){m^3} \cr & = 44\,{m^3} \cr} $$
