In a shower, $5 \mathrm{cm}$ of rain falls. The volume of the water that falls on $2$ hectares of ground, is 

The diameter of base of a cylinder is $4 \mathrm{cm}$ and its height $14 \mathrm{cm}$. The volume of the cylinder is 

[Take $\mathrm{\pi }=\frac{22}{7}$]

The diameter of a cylinder is $28 \mathrm{cm}$ and its height is $20 \mathrm{cm}$. The total surface area of the cylinder is 

The height of a cylinder is $14 \mathrm{cm}$ and curved surface area is $264 {\mathrm{cm}}^2$. The volume of the cylinder is 

The curved surface area of a cylinder pillar $264 {\mathrm{m}}^2$ and volume is $924 {\mathrm{m}}^3$. The height of the pillar is (use $\pi =\frac{22}{7}$)

[Take $\mathrm{\pi }=\frac{22}{7}$]

The ratio between the radius of the base and the height of the cylinder is $2:3$. If its volume is $1617 {\mathrm{cm}}^3$, the total surface area of the cylinder is
