circ = diam x pi
When you double the diameter, the circumference is also doubled.
Since the equation for circumference is pi*d then if you double the diameter the circumference will be doubled.
It will make the circumference of the circle bigger or smaller
The circumference also doubles.
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
three times
Circumference and diameter are directly proportional. Doubling one doubles the other, and the same applies for any multiplier.
A circle with a circumference of 11.25 has a diameter of: 3.581
The circumference of a circle with a diameter of 25 is: 78.54
If the diameter of a circle is 9 the circumference is: 28.3
