The circumference of the circle is 16.
The ratio of the area to the circumference of a circle is 5/4.
Now, to find the circumference of the circle.
So, we get radius(r) first to find circumference.
For, getting radius(r) we use the proportion:
Now, putting formula to solve it:
On solving we get:
By multiplying with 2 on both sides we get:
Radius = 2.5.
Now, putting the formula to get the circumference:
Taking the value of π = 3.14.
Circumference = 16 (approximately).
Therefore, the circumference of the circle is 16.
