Right formula, wrong answer.The answer is 1520mm and the formula is Pi r square,(since I can't put the symbols on here)! Any 6th grader would know that but you act like I'm talking rocket science! Tell me some more about how uneducated Republicans are! My God?

Pi (3.14) x 22 (radius)= 69.08 x 2 (squared)= 138.16

OR you can do it this way

22 (radius) x2 (squared)= 44 x 3.14 (pi)= 138.16

I havent a clue how u arrived at your answer.
