Answer:
Surface area of cone is
Step-by-step explanation:
Given:
radius of a cone (r) = 8 feet
slant height of cone (l) = 12 feet
We need to find the surface area of cone.
Total surface area of cone = Area of circle Area of curved surface
Now we know that,
Area of circle =
Area of curved surface =
Hence Total surface area of cone =
Surface area of cone is .
