Square footage of a circle:

*

Find the center point of the circle.
*

Measure from that point to the edge of the circle to determine the radius.
*

Multiply the radius by itself.
*

Then multiply that number by PI (3.14) to find the area of your circle.

So 275 X 275 X 3.14 = 237,462.5 mm
which equals 2.556025 square feet

I used this to convert mm to feet http://www.ilpi.com/msds/ref/areaunits.html
