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
