Answer:

$200 \: \pi$

Explanation:

Given,

R = 8 m

H = 15 m

Slant height :

$= \sqrt{ {r}^(2) + {h}^(2) }$

$= \sqrt{ {(8)}^(2) + {(15)}^(2) }$

$= \sqrt{ {(17)}^(2) }$

$= 17 \: m$

Now, Finding the surface area of the cone:

$\pi \: r(r + s)$

Plugging the values:

$= \pi \: * 8(8 + 17)$

$= 8\pi \: * 25$

$= 200 \: \pi$

Hope this helps...

Good luck on your assignment...
