Vedclass · Answer

(A) For the given cone,the radius $r = 5\,cm$ and the height $h = 12\,cm$.First,we calculate the slant height $l$ using the formula $l = \sqrt{r^2 + h^2}$.$l = \sqrt{5^2 + 12^2} = \sqrt{25 + 144} = \sqrt{169} = 13\,cm$.The $CSA$ (Curved Surface Area) of a cone is given by $\pi r l$.The area of the base of the cone is $\pi r^2$.Therefore,the ratio of the $CSA$ to the area of the base is $\frac{\pi r l}{\pi r^2} = \frac{l}{r}$.Substituting the values,we get $\frac{13}{5}$,which is $13:5$.

The radius and height of a cone are $5\,cm$ and $12\,cm$ respectively. Then,the ratio of its $CSA$ and area of base is $\ldots \ldots \ldots \ldots$
