Answer:

[tex]200 \pi[/tex]

This is the 4th and last choice

Step-by-step explanation:

  • Let's write down the formula for the surface area of a cone A, given radius r and height h
    [tex]A = \pi r(r + \sqrt{r^ 2+ h^2})\\\\[/tex]
  • Plugging in values for r and h we get
    [tex]A = \pi 8(8 + \sqrt{8^ 2+ 15^2})\\\\= \pi 8( 8 + \sqrt{64+ 225})\\\\= \pi 8(8 + \sqrt{289})=\pi 8 (8 + 17)\\\\= \pi 8 (25)\\\\= \pi (200)\\\\= 200 \pi\\\\\text {4th choice}[/tex]
