I'm so lost on this one can. Can someone explain how you get to this answer.
((1/2)(8^2)((4PI)/9)) Evaluates/Simplified to ((32PI)/9) Thanks in advance |

Without the 4π at the top, you'd get (32π/9), but that's not the correct answer. With what you've posted you should get (128π/9).

Is the problem "one-half times 8 squared times 4π over 9"? If it's that then the answer in the back of the book is wrong.
