Answer is below.
Step-by-step explanation:
Using the formula for circumference using area, we can plug in the area and solve backwards for the circumference.

Answer:
28.35
Step-by-step explanation:
Area = pi × r²
64 = 3.14 × r²
r² = 64/3.14
r = 4.514661184
Circumference = 2 × pi × r
2 × 3.14 × 4.514661184
28.35207223
