The area of a circle is PI times the radius squared.

If the diameter is 21 feet, the radius is half that or 10.5 feet.

Area = PI * 10.5 * 10.5 = 346.36059 square feet

The area of a circle can be calculated using the formula: A = πr^2. If the diameter is 21ft, the radius would be half of that, which is 10.5ft. The area of the circle would be approximately 346 square feet.
