Question

* ANSWER PLS TY!! * Find the surface area of this cone.

Answer 1

Answer:

$200 \: \pi$

Step-by-step explanation:

Given,

R = 8 m

H = 15 m

Slant height :

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

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

$= \sqrt{64 + 225}$

$= \sqrt{289}$

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

$= 17 \: m$

Now, Finding the surface area of the cone:

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

Plugging the values:

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

$= 8\pi \: \times 25$

$= 200 \: \pi$

Hope this helps...

Good luck on your assignment...
