Question

What is the surface area of the cone to the nearest whole number? Use 3.14 for Π.

Answer 1

`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`
