A=pi%2Ar%5E2 Start with the area of a circle formula.


A=pi%2A%286%29%5E2 Plug in r=6 (note: the radius is half the diameter).


A=%283.14159265%29%2A%286%29%5E2 Replace pi with 3.14159265 (note: Use more digits of pi to get better accuracy).


A=%283.14159265%29%2A%2836%29 Square 6 to get 36.


A=113.0973354 Multiply 3.14159265 and 36 to get 113.0973354 (this figure is approximate).


A=113 Round to the nearest foot.


So the area is roughly 113 square feet.
