The center of a soccer field has an area of 100m squared. find the circumference of the center circle.

The formula for the area of a circle is A=πr². To find the circumference, we must find the radius, r. To do this, we plug in the area for A in the first formula, then plug it in to the circumference formula:


Now we know that r=10 meters. Now we plug this into the circumference formula, C=2πr.


The answer is 20π meters.

Hope this helps!

The answer is all about the number 4
