The circumference of the base of a cylindrical vessel is $132 \,cm$ and its height is $25 \,cm$. How many litres of water can it hold (in $,l$)? $(1000 \,cm^3 = 1 \,l)$ Assume $\pi = \frac{22}{7}$.

Find the surface area of a sphere of radius $5.6 \, cm$.
Assume $\pi = \frac{22}{7}$. (in $, cm^{2}$)

Shanti Sweets Stall was placing an order for making cardboard boxes for packing their sweets. Two sizes of boxes were required. The bigger of dimensions $25 \,cm \times 20 \,cm \times 5 \,cm$ and the smaller of dimensions $15 \,cm \times 12 \,cm \times 5 \,cm$. For all the overlaps,$5\%$ of the total surface area is required extra. If the cost of the cardboard is $Rs. 4$ for $1000 \,cm^2$,find the cost of cardboard required for supplying $250$ boxes of each kind.

The inner diameter of a circular well is $3.5\, m$. It is $10\, m$ deep. Find the cost of plastering this curved surface at the rate of $Rs. 40$ per $m^2$.

Find the volume of a sphere whose radius is $0.63 \, m$. Assume $\pi = \frac{22}{7}$. (in $, m^3$)

If the lateral surface area of a cylinder is $94.2 \, cm^2$ and its height is $5 \, cm$,then find its volume. (Use $\pi = 3.14$) (in $, cm^3$)
