First divide the area by 3.14. Which is 441. 441 is your radius squared. Then you have to find the root of 441 which is 21. 21 is your radius. Then you must add 21 to 21 to find your diameter. That is 42. Then plug 42 in your circumference formula. Which is then C= 3.14 (42). Which means the circumference is 131.88.
