The ratio of the area to the circumference of a circle is 5/4. what is the circumference of the circle?

The circumference of the circle is 16.

Step-by-step explanation:

Given:

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.
