Ah, what a happy little question! When the circumference of a circle is 2.5 inches, we can find the diameter by using a simple formula: diameter = circumference / π. So, the diameter would be 2.5 inches divided by π, which is approximately 0.796 inches. Just like painting a beautiful landscape, math can be a peaceful journey of discovery!

To find the diameter when given the circumference, you can use the formula for the circumference of a circle: C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter. Given that the circumference is 2.5 inches, you can plug this value into the formula: 2.5 = πd. Solving for d, you get d ≈ 0.796 inches.
The diameter of a circle with a circumference of 25 inches is: 78.54 inches. (d = c divided by Pi).
25*pi inches
It is: 25/pi which is about 8 inches
C = ~78.54 inches.
The diameter of a circle with a circumference of 2.75 inches is: 0.875 inches (circumference divided by pi = diameter).
