Find the area of a circle with diameter 8 in. Use the value 3.14 for n, and do not round your answer.
Be sure to include the correct unit in your answer.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
