Answer:
AREA = 4π m²÷4 = 12.56 m²
12.56 m² is the circumference
of the circle
9514 1404 393
4π m
Explanation:
The area is given by ...
A = πr²
Then the radius is ...
r = √(A/π) = √(4π/π) = 2 . . . . meters
The circumference is ...
C = 2πr
C = 2π(2 m) = 4π m
The circumference of the circle is 4π meters.
