(B) The relationship between the arc length $(l)$,the radius $(r)$,and the angle subtended at the centre in radians $(	heta)$ is given by the formula: $l = r 	heta$.Given:Arc length $(l)$ = $15 \ cm$Angle $(	heta)$ = $3/4 \ 	ext{radian}$Substituting the values into the formula:$15 = r 	imes (3/4)$$r = 15 	imes (4/3)$$r = 5 	imes 4$$r = 20 \ cm$.Therefore,the radius of the circle is $20 \ cm$.

The radius of the circle whose arc of length $15 \ cm$ makes an angle of $3/4$ radian at the centre is ..... $cm$.
