The diameter of a circle is doubled if the circumference is doubled.
Since the equation for circumference is pi*d then if you double the diameter the circumference will be doubled.
If you double the circumference. the diameter like wise would double.
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
The circumference of a circle if the diameter is 12cm is 37.7cm
The diameter of a circle is doubled if the circumference is doubled.
Since the equation for circumference is pi*d then if you double the diameter the circumference will be doubled.
Circumference and diameter are directly proportional. Doubling one doubles the other, and the same applies for any multiplier.
The circumference is doubled or tripled, respectively.
When the diameter of the circle doubled, its circumference also doubled.However, its area increased to 4 times the original area, while nobody was looking.
If you double the circumference. the diameter like wise would double.
First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .
The circumference of a circle is diameter times pi or pi times the radius doubled. Pi is equivalent to 22/7. Multiply 21 by 3.14 which gives you 65.999999... 7
The area increase by four times.
The circumference also doubles.
It will make the circumference of the circle bigger or smaller
If the diameter of a circle is 69mm then the circumference is: 216.8mm (diameter x pi = circumference).
