Answer:

The surface area of the cone
=238.64feet^2

Explanation:

The given figure is in the shape of a cone:

$Diameter=8 feet\\\\Radius=8/2=4 feet$

slant height(l)
=15 feet

Surface area of the cone

=
$\pi rl+\pi r^2$

As,
$\pi =(22)/(7)=3.14$

Surface area of the cone =
(3.14*4*15)+(3.14 *4*4)

$=(3.14*60)+(3.14*16)\\\\=188.4+50.24\\\\$

=238.64feet^2

The surface area of the cone
=238.64feet^2
