12 inch diameter(also 6 inch radius).
12 inch diameter(also 6 inch radius).
Diameter = Circumference/pi = 38/pi = 12.1 inches
The circumference of a 6 inch diameter circle is: 18.8 inches. (diameter x Pi = circumference)
The circumference of a six-inch diameter circle is: 18.8 inches.
The circumference of 9 inch diameter circle is about 28.27 inches.
The circumference of a circle with a 20.5 inch diameter is 64.4 inches.
The circumference of a circle with a 39 inch diameter is 122.52 inches.
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
If the circumference is 38, the diameter is 38/pi. Since the radius is half of the diameter, the radius is 19/pi.
The diameter is about 12.1
circumference = pi*diameter so diameter = circumference/pi = 4.456 inches
