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

$SA=2,512\ m^2$
