Question

7 I got v=414.7

I don't understand why I'm getting the wrong answer

I used the formula pir^2h/3

Answer 1

Problem is, 11' is not h (height), but the slant height.
You need to calculate the height using Pythagoras theorem, namely
\(h^2+6^2=11^2\)
after solving for h, you can continue with the volume formula you used earlier.
