First of all, there's no such thing as the "area of a circumference". The distance
around the circle is called the "circumference", and the area of the circle is called
the "area of the circle".
-- When the diameter of the circle is doubled, the circumference is doubled
and the area is multiplied by 4.
-- When the diameter of the circle is tripled, the circumference is tripled
and the area is multiplied by 9.
-- When the diameter of the circle is multiplied by N, the circumference is
multiplied by N and the area is multiplied by N2 .

What happens to the diameter if the circumference is doubled?
The diameter of a circle is doubled if the circumference is doubled.
How would the circumference of a circle change if you doubled its diameter?
When you double the diameter, the circumference is also doubled.
When the diameter of a circle doubled what happens to the circumference of the circle?
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.
What happens to the circumference when the diameter of a circle is doubled or triple?
The circumference is doubled or tripled, respectively.
What happens to the area of a circle when its doubled?
When the diameter is doubled, perhaps? Then the area is 4 x larger.
If the circumference of a circle is doubled what happens to the diameter?
If you double the circumference. the diameter like wise would double.
What happens to the area of a circle when the diameter is doubled?
the area is increased by 4 times
If the circumference of a circle is doubled how does the diameter of the circle change?
Circumference and diameter are directly proportional. Doubling one doubles the other, and the same applies for any multiplier.
How does the circumference of a circle change if you double its diameter?
Since the equation for circumference is pi*d then if you double the diameter the circumference will be doubled.
What happens to the area of a circle if the diameter is doubled?
If you double the diameter of a circle, the area will quadruple (be 4x greater).The area of the circle increases exponentially with the diameter, or more precisely with the radius, which is 1/2 the diameter. A = (pi)r2Doubling the diameter of a circle will quadruple the area (22 =4).This is easily seen in pizzas, where the dough needed for a 16-inch pizza can be used instead to make 4 pizzas with a diameter of 8 inches.---The equation to find the area of a circle is a=(pi)r2. If the diameter is doubled, then the radius is also doubled, because the radius is just half the diameter.The area of a circle once its radius (and therefore diameter) has been doubled can be expressed as follows: a'=(pi)(2r)2, which simplifies to a'=(pi)(4r2).To find the proportion of a' and a, we just divide the second by the first. This gets us[(pi)(4r2)]/[(pi)(r2)]=4
What happens to the area of the circle when the diameter is doubled?
As the area of a circle A equals pi times the radius squared, and doubling the diameter means multiplying the radius by four, the area is multiplied by 16 when you double the diameter.
If a circle has the diameter of 21 what is the circumference?
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
