Vedclass · Answer

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