The circumference of a circle, if the diameter is 9.5 inches, is: 29.85 inches (diameter x Pi = circumference)
If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).
The diameter of a circle with circumference of 25.56 inches is: 8.136 inches (diameter x Pi = circumference).
If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
If a circle has a diameter of 24 inches its circumference is: 75.4 inches (diameter x Pi = circumference).
If the circumference of a circle is 10 inches, the diameter is: about 3.183 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).
11 is a good approximation of the diameter. If the circumference is 35, the actual diameter is about 11.14 (35/3.1416).
