32pi/96 = pi/3

0.333333 is not a good answer, because it is a decimal approximation. 1/3 is exact, so it is better.

And the answer still includes pi.

If the correct answer really is 3pi (not just 3), then perhaps you made an error earlier in your work to end up with your proportion "upside down".

whoever told you,%2832pi%29%2F96 is not equal to 3

proof:
%2832pi%29%2F96
=pi%2832%2F96%29
=pi%281%2F3%29%29%0D%0A%0D%0A=%7B%7B%7Bpi%2A0.3333333333333%29
=3.14%2A0.3333333333333%29
=1.046666666666562

if you round decimals to whole numbers, you get 3%2832%2F96%29=1
