~Hello There!~
The formula to find the area of a circle is:
We already know this answer, so we write it as:
We need to calculate the radius (r) from this so divide both sides by 
Square root this to get r
r = 3.949327085
The formula for circumference is 
(d is the diameter )
Double the radius to get the diameter:
d = 7.89865417
Multiply this value by to get the answer
The circumference is 24.81435391
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
