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.
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 area increase by four times.
the area of the circle is increased by 400%
When the diameter is doubled, perhaps? Then the area is 4 x larger.
It quadruples.
The area quadruples.
the area is increased by 4 times
The area of a circle with a circumference of 9.42 is about 7.06.
You dived the area by the circumference of the circle.
No,Circumference is like the perimiter and Area is the whole circle.
If the circumference of a circle is 6.28 then its area is about 3.138 square units
