A circle with a diameter of 12 inches has an area of ~113.1 square inches.
If a circle has a diameter of 12 inches the circumference will be about 37.7 inches. (C = d x Pi)
12 inches because the radius is half of the diameter, and 6 x 2 is 12.

Frisbees come in different sizes. The diameter can be 8 inches, 10 inches, 12 inches, or another diameter.
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
Circumference = 37.7 inches Diameter = 12 inches
