The radius of a wheel is $0.25\, m$. The number of revolutions it will make to travel a distance of $11\, km$ will be

If the altitude of an equilateral triangle is $12 \sqrt{3} \text{ cm}$,then its area would be

In the given figure, $ABCDEF$ is a regular hexagon whose side is $6\, cm$. $APF$, $QAB$, $DCR$, and $DES$ are equilateral triangles. What is the area (in $cm^2$) of the shaded region (in $\sqrt{3}$)?

$A$ rectangular plot is $180 \, m^2$ in area. If its length is $18 \, m$,then its perimeter is ...... $m$?

The perimeter of a circle is equal to that of a square. Compare their areas.

$A$ rectangular park is $65\, m$ long and $50\, m$ wide. Two cross paths,each $2\, m$ wide,are to be constructed parallel to the sides. If these paths pass through the centre of the rectangle and the cost of construction is ₹ $17.25$ per $m^2$,then find the total cost involved in the construction (in ₹).
