Answer:
The circumference of the circle is 6 cm (approximately).
Step-by-step explanation:
Given:
Area of the circle = 1/4π²
Now, to get the circumference of the circle we need the radius.
So, finding the radius by putting the formula of area:
Area = 
=
dividing π by both sides:


using square root on both the sides:

So, the radius is 
Now, putting the formula of circumference:

=
=
putting the value of π =3.14
=
=
=
Circumference = 5.56 cm
Therefore, the circumference of the circle is 6 cm (approximately).
Poorly phrased question, but the general answer is 5k/(12k), where k <span>∈ Z (i.e. k is an integer).
So, 5/12 and 10/24.</span>
