Vedclass · Answer

(C) The total surface area of a cone consists of the sum of the curved surface area and the area of the circular base.$1$. The curved surface area of a cone is given by $\pi r l$,where $r$ is the radius and $l$ is the slant height.$2$. The area of the circular base is $\pi r^{2}$.$3$. Therefore,the total surface area $= 	ext{Curved surface area} + 	ext{Base area} = \pi r l + \pi r^{2}$.$4$. Factoring out $\pi r$,we get $\pi r(l + r)$.Thus,the correct option is $C$.

The total surface area of a cone is equal to $\ldots \ldots \ldots \ldots .$
