Find the area of the minor segment of a circle of radius $14\,cm$, when the angle of the corresponding sector is $60^{\circ} .$ (in $cm ^{2}$)
The formula to find the length of a major arc of a circle is ............
In $\odot( O ,\, 5.6), \overline{ OA }$ and $\overline{ OB }$ are radii perpendicular to each other. Then, the difference of the area of the minor sector formed by minor $\widehat{ AB }$ and the corresponding minor segment is $\ldots \ldots \ldots \ldots cm ^{2}$.
In a circle with radius $14 \,cm ,$ the area of minor sector corresponding to minor $\widehat{ ACB }$ is $77 \,cm ^{2}$. Then, minor $\widehat{ ACB }$ subtends an angle of measure $\ldots \ldots \ldots \ldots$ at the centre.
