The area of the circle above is 1,384.74 units2. what is the circumference of the circle? use = 3.14.

Radius 21
circumference 131.88

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.

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
