2 feet
diameter = 2 x radius
diameter = 2 x 12 inches = 2 x 1 foot = 2 feet
Since your circle has a diameter of 9 feet (the definition of a "9 by 9" circle), the radius is half of that distance. In this case, your radius is 4.5 feet or 54 inches.
As the diameter of a circle is twice the radius, a circle with a 6-foot radius would have a diameter of 6 x 2 or 12 feet.
The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
A radius of a circle is from the center to the edge. A diameter goes from edge to edge across the center, so the diameter is twice the radius. 8.5 feet. ■
Your questions is not solvable the way you wrote it. If you mean, "What is the radius of a circle with a diameter or 6 feet?" , then the answer is 3 feet. Reason is because the radius of a circle is half of its diameter.
If 6 feet 6 inches is its diameter then its radius is 3 feet 3 inches

As the diameter of a circle is twice the radius, a circle with a 6-foot radius would have a diameter of 6 x 2 or 12 feet.
If the radius is 8 feet then the diameter will be 16 feet.
The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
