Answer:
The surface area of the cone is;
68 π m^2
Step-by-step explanation:
Here, we want to get the surface area of the cone
Mathematically, we have this as ;
S.A = π(r^2 + rl)
where r is the radius and l is the slant height
We are given the diameter, but the radius is half of this
d = 8
r = d/2 = 8/2 = 4 m
l = 13 m
S.A = π(4^2 + 4(13))
= π(16 + 52) = 68 π m^2
