Vedclass · Answer

(C) The formula for the angle $	heta$ subtended by an arc of length $l$ at the centre of a circle of radius $r$ is given by $	heta = \frac{l}{r}$,where $	heta$ is in radians.Given,radius $(r) = 3 	ext{ m}$ and arc length $(l) = 1 	ext{ m}$.Substituting these values into the formula:$	heta = \frac{1}{3} 	ext{ radian}$.Therefore,the correct option is $C$.

The angle subtended at the centre of a circle of radius $3 \text{ m}$ by an arc of length $1 \text{ m}$ is equal to
