The diameter of a circle that has a circumference of 125 centimeters is: 39.79 cm (circumference divided by Pi = diameter).
If the diameter of a circle is 18 centimeters the circumference will be about 56.55 cm (d x Pi = C)
The circumference of a circle with a diameter of 39 centimeters is about 122.5 cm (C = d x Pi)
The circumference of a circle with a diameter of 30 centimeters is: about 94.25 cm. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
Well, isn't that just a happy little question! To find the diameter of a cylinder when you know the circumference, you can use the formula: diameter = circumference / π. So, for a circumference of 45 centimeters, the diameter would be 45 / π ≈ 14.32 centimeters. Just remember, there are no mistakes, just happy little accidents in math!
