In $\odot( O , 7),$ the length of $\widehat{ ABC }$ is $14 .$ Then, $\ldots \ldots .$ holds good.
$\overline{ AC }$ is a diameter
$\widehat{ ABC }$ is a minor arc
$\widehat{ ABC }$ is a major arc
$\widehat{ ABC }$ is a semicircle
Find the radius of a circle whose circumference is equal to the sum of the circumferences of two circles of radii $15 \,cm$ and $18 \,cm$ (in $cm$)
Is it true to say that area of a segment of a circle is less than the area of its corresponding sector? Why?
The length of the minute hand of a clock is $12\,cm .$ The area of the region swept by it in $5$ minutes is $\ldots \ldots \ldots . . cm ^{2} .(\pi=3.14)$
Will it be true to say that the perimeter of a square circumscribing a circle of radius $a \,cm$ is $8 a \, cm ?$ Give reasons for your answer.
In $\odot( O , 6), \widehat{ ABC }$ is a major arc and $m \angle AOC =60 .$ Then, the length of major $\widehat{ ABC }$ is ...........
