The diameter of a circle is doubled if the circumference is doubled.
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 is tripled.C=pi*d, so pi*(3d) = 3C, where d is diameter and C is 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.
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.
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.
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 .
Circumference and diameter are directly proportional. Doubling one doubles the other, and the same applies for any multiplier.
The circumference of a circle divided by its diameter is equal to the value of pi
It becomes twice as large
The circumference is also quadrupled.
It quadruples.
When the diameter is doubled, perhaps? Then the area is 4 x larger.
