Answer:

area = 144\pi

Step-by-step explanation:

volume =  \frac{4}{3} \pi {r}^{3}  \\  \\ 288\pi =  \frac{4}{3} \pi {r}^{3} \\  \\ 3(288\pi) = 4\pi {r}^{3} \\  \\  \frac{3(288\pi)}{4\pi}  =  {r}^{3}  \\  \\ 216 =  {r}^{3}  \\  \\ r =  \sqrt[3]{216}  \\ r = 6

area = 4\pi {r}^{2}  \\ area = 4\pi ({6}^{2})  \\ area = 144\pi
