Answer:
[tex]SA=264\pi\ m^{2}[/tex]
Step-by-step explanation:
we know that
The surface area of the composite figure is equal to
[tex]SA=2[\pi rl]+2\pi rh[/tex]
we have
[tex]r=6\ m[/tex]
[tex]l=8\ m[/tex] ----> slant height of the cone
[tex]h=14\ m[/tex] ---> height of the cylinder
substitute
[tex]SA=2[\pi (6)(8)]+2\pi (6)(14)[/tex]
[tex]SA=96\pi+168\pi[/tex]
[tex]SA=264\pi\ m^{2}[/tex]
