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.
The circumference also doubles.
It will make the circumference of the circle bigger or smaller
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.
If a circle has a diameter of 19, the circumference is: 59.7 (diameter x Pi = circumference)
The circumference of any circle is (pi) x (its diameter). If diameter = 1 then Circumference = pi .
The circumference of a circle if the diameter is 12cm is 37.7cm
