10.1#6

Hi, I have tried this problem numerous times and even gone to Google to see what the world says, and I can't figure out why I am wrong. I am confident the radius^2 is 14, so am I doing the center point wrong? Maybe I could get this broken down better? Let me know.

yes, you just got tangled in the arithmetic because the halfway point between 1 and 5 is 3 not 2.
