Vedclass · Answer

(b) Given that diameter of circular wire $= 14\,cm$

Therefore length of circular wire $= 14 \pi\, cm.$

$	herefore $ Required angle $ = \frac{{{m{arc}}}}{{{m{radius}}}} = \frac{{14\pi }}{{12}} = \frac{{7\pi }}{6}$

$ = \frac{7}{6}\pi .\frac{{{{180}^o}}}{\pi } = {210^o}$.

A circular wire of radius $7\,cm$ is cut and bend again into an arc of a circle of radius $12\,cm$. The angle subtended by the arc at the centre is ......$^o$
