Answer:

AREA = 4π m²÷4 = 12.56 m²

12.56 m² is the circumference

of the circle

9514 1404 393

Answer:

  4π m

Step-by-step 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.
