Answer:
The surface area of the cone[tex]=238.64feet^2[/tex]
Step-by-step explanation:
The given figure is in the shape of a cone:
[tex]Diameter=8 feet\\\\Radius=8/2=4 feet[/tex]
slant height(l)[tex]=15 feet[/tex]
Surface area of the cone
=[tex]\pi rl+\pi r^2[/tex]
As, [tex]\pi =\frac{22}{7}=3.14[/tex]
Surface area of the cone =[tex](3.14*4*15)+(3.14 *4*4)[/tex]
[tex]=(3.14*60)+(3.14*16)\\\\=188.4+50.24\\\\[/tex]
[tex]=238.64feet^2[/tex]
The surface area of the cone[tex]=238.64feet^2[/tex]
