What is the area of a circle with diameter of 22 ft?

Oh, what a happy little question! To find the area of a circle, we use the formula A = πr^2. Since the diameter is 22 ft, the radius (which is half the diameter) would be 11 ft. Plugging that into the formula, we get an area of approximately 380.13 square feet. Just imagine all the happy little trees you could fit in that space!
