Answer:


SA=2,512\ m^2

Explanation:

we know that

The surface area of the cone is equal to


SA=\pi r^(2)+\pi rl

where

r is the radius

l is the slant height

we have


r=32/2=16\ m ----> the radius is half the diameter


l=34\ m


\pi =3.14

substitute the values in the formula


SA=(3.14)(16)^(2)+(3.14)(16)(34)


SA=803.84+1,708.16


SA=2,512\ m^2
