Step-by-step explanation:
The radius is 8
=16/2
=8
![SA=2\pi rh+2\pi r^2\\=2(\pi )(8)(9)+2(\pi)(8)^2\\=2(\pi )(72)+2(\pi )(64)\\=(144)\pi +(128)\pi \\=272\pi](https://tex.z-dn.net/?f=SA%3D2%5Cpi%20rh%2B2%5Cpi%20r%5E2%5C%5C%3D2%28%5Cpi%20%29%288%29%289%29%2B2%28%5Cpi%29%288%29%5E2%5C%5C%3D2%28%5Cpi%20%29%2872%29%2B2%28%5Cpi%20%29%2864%29%5C%5C%3D%28144%29%5Cpi%20%2B%28128%29%5Cpi%20%5C%5C%3D272%5Cpi)
