In a circle with radius $7 \, cm$,the area of a minor sector can be $\ldots \ldots \ldots \ldots \, cm^{2}$.

$A$ chord of a circle of radius $10\, cm$ subtends a right angle at the centre. Find the area of the corresponding:
$(i)$ minor segment $\&$ $(ii)$ major sector. (Use $\pi=3.14$ )

The radius of a circular ground is $35 \, m$. Outside it,a road of width $3.5 \, m$ runs around it. Find the area of the road in $m^2$.

In the figure,$ABCD$ is a trapezium with $AB \parallel DC$,$AB = 18 \, cm$,$DC = 32 \, cm$,and the distance between $AB$ and $DC = 14 \, cm$. If arcs of equal radii $7 \, cm$ with centers $A, B, C$,and $D$ have been drawn,find the area of the shaded region of the figure (in $cm^2$).

In a circle,the length of a minor arc is $110 \,cm$ and it subtends an angle of measure $150^{\circ}$ at the centre. Then,the radius of the circle is $\ldots \ldots \ldots \ldots \,cm$.

Area of a circle is $5544 \, cm^{2}$. Find its radius (in $cm$).
