See below
Step-by-step explanation:
Given the area A you can find the radius of a circle.
A = πr^2
so r^2 = A / π
and r = the positive square root of A/π.
Having found the radius r you can calculate the circumference C using
C = 2πr.

use the formula of a circle or pi times radius r squared = Area then use the formula for the circumfrence of a circle which is two times pi time radius r = circumfrence then isolate r in the formula (for area)
sqrt (A/pi) then multiply the raduis r by 2*pi to get the circumference
C = 2*pi*sqrt (A/pi)
