Answer 1

Answer:

The surface area of the cone$=238.64feet^2$

Step-by-step 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, $\pi =\frac{22}{7}=3.14$

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$=238.64feet^2$
