(C) The formula for the curved surface area of a cylinder is $2 \pi r h$.Given that the curved surface area is $132 \, cm^2$ and the height $h = 3 \, cm$.Substituting the values into the formula:$132 = 2 	imes \frac{22}{7} 	imes r 	imes 3$$132 = \frac{132}{7} 	imes r$Multiplying both sides by $\frac{7}{132}$:$r = 132 	imes \frac{7}{132} = 7 \, cm$.The diameter $d$ is twice the radius:$d = 2r = 2 	imes 7 = 14 \, cm$.

The curved surface area of a cylinder is $132 \, cm^2$. If its height is $3 \, cm$,its diameter is $\dots \dots \dots \, cm$.
