The circumferences of two circles are $132 \text{ m}$ and $176 \text{ m}$ respectively. What is the difference between the area of the larger circle and that of the smaller circle (in $\text{m}^2$)?

The dimensions of the floor of a rectangular hall are $4\, m \times 3\, m$. The floor of the hall is to be tiled fully with $8\, cm \times 6\, cm$ rectangular tiles without breaking the tiles into smaller sizes. The number of tiles required is:

In the adjacent figure,find the area of the shaded region in $cm^2$. (Use $\pi = 22/7$)

How many times will a wheel of diameter $105\, cm$ rotate in covering a distance of $330\, m$? (in $revolutions$)

The area of a field in the shape of a trapezium is $1440 \, m^2$. The perpendicular distance between its parallel sides is $24 \, m$. If the ratio of the parallel sides is $5:3$, the length of the larger parallel side is ....... $m$.

Find the area of the shaded region if the radius of each of the circles is $1\, cm$.
