A = (pi)r^2
C = 2(pi)r
C = 2(pi)r

I'm sorry I don't understand how to incorporate those equations into finding the answer

first off, the circumference is measured in meters, not m^2.
If C = 2π^2, then
2πr = 2π^2
r = π
So, A = πr^2 = π^3 m^2
If you meant to find the circumference when the area is 2π^2 m^2,
πr^2 = 2π^2
r^2 = 2π
r = √2π
C = 2πr = 2π√2π = (2π)^(3/2)
Actually, I think you just messed up the whole question.
