Find the area of a circle with a circumference of 2 pie

We know that formula for circumference is 2πr

Since we have circumference of 2π, that would means 2π = 2πr.

We need to solve for r. We can divide both sides by 2π:

2π / 2π = 2πr / 2π

1 = r

So radius is 1.

Now the formula for area of circle is πr². So plug in r=1 and that would be 

π(1)²

π

So area of circle is π.

Hope this helps.

What is the radius? you will need to find the radius first
