11.994 inches
Circumference is 2 x pi x radius, so I know that 37.68 = 2piR
Since 2 and pi are constants, I divide both sides by 2, and then by pi.
This gives me R all by itself on one side, and the length of the radius on the other side. The radius was 5.997, or about six.
Since the radius is half the diameter, I then multiplied the length of the radius by two. This gave me 11.994, or about 12 inches
3768 cm. C= pi x Diameter, so 3.14 x 1200.
If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).
If a circle has a diameter of 12.8 inches its circumference is: 40.21 inches (circumference = diameter x Pi).
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
If the circumference of a circle is 75 inches, the diameter is: about 23.87 inches. (diameter = circumference divided by pi).
3768 cm. C= pi x Diameter, so 3.14 x 1200.
The circumference of a circle, if the diameter is 9.5 inches, is: 29.85 inches (diameter x Pi = circumference)
