Answer 1

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`
