Answer:
[tex] \boxed{\sf Surface \ area \ of \ the \ cone = 24\pi \ m^{2}} [/tex]
Given:
Slant height (l) = 5 m
Radius (r) = 3 m
To Find:
Surface area of the cone
Step-by-step explanation:
[tex] \sf Surface \: area \: of \: the \: cone = \pi {r}^{2} + \pi rl \\ \\ \sf = \pi r(r + l) \\ \\ \sf = \pi \times 3(3 + 5) \\ \\ \sf = \pi \times 3(8) \\ \\ \sf = \pi \times 24 \\ \\ \sf = 24\pi \: {m}^{2} [/tex]
